On the technical sheet it is the 371equivalent (370). The technical sheet is from ETA who make the movement. And since the case is made by breitling, they have made the caseback to accommodate a thicker battery for longer service intervals. This is my assumption. So the round well on the caseback is there to also accommodate a thicker long life battery (399 or 395)

As a former High School advanced electronics teacher, quartz movement time pieces were part of my lecture regarding piezo electricity and electromagnetism. Some of them can generate a frequency so high, it breaks one second into 30k parts and that is what makes them so accurate. The are truly a marvel of electrical engineering.

For what you said at 3:40 - The first watch I bought from my own money, back then as a fresh employee was a Timex Quartz watch with thermometer a compass fucntion. I was so happy I bought it with my own money and I was looking at the time every couple of minutes. I still have it, and when I look at it it reminds me of how I felt at the time. Anyway, beautiful video!

Also to me I see this as an art, and this is something that should never die out no matter how technology progresses. I hope your son learns from you!

Spot on! I bought a Seiko quartz with my very first pay packet over 30 years ago. I still have it. 🙂✌️

I cannot get enough of these episodes. I like to play them as I am working; almost like meditation with some comedy thrown in randomly. :-)

Love that you are showing the “little one” the methods and procedures. Even if he doesn’t follow you in the horological arts it is a skill he can use in so many ways. Best Dad Ever!!!

It is so frigging cool how you're teaching your kids about what you do.

It doesn’t matter how a watch is powered as long as the person wearing it loves it, it will have a happy life.

Such a treat! Thank you for doing this for us. You’re KZfaq’s best watchmaker. Best from Edinburgh.

Your voice is one of the most relaxing I've ever heard. I love watching, and listening to you work. Many thanks for taking the time to make content for us.

Having enjoyed watching you work on purely mechanical watches, I decided to watch this one too. Just as impressive as the others: you have a way with words, a great sense of humour and you are a fantastic teacher.

14:00 when you popped open that Brietling packet I thought "now that LCD will have cost an arm and a leg!"

This was awesome ! Been on the fence for awhile about having my grandfather’s. ‘ 79 Seiko SQ quartz restored . After watching this I’m going to go ahead and do it .

Beautiful! I personally have nothing against quartz watches. I've worn many, and they're very practical. But I've been a mechanical tick-tock watch and clock lover since very early childhood. Some of the first things I would take apart trying to figure out out how they work were my grandpa's broken pocket watches. He'd break one, buy a new one and give me the broken one to play with because as a child I loved taking things apart to figure them out. Now 50 years later, the swinging pendulums and swaying balance wheels have a romantic place in my heart that nothing else can replace.

I've had one of these for over 20 years and it's never skipped a beat. Utterly reliable and useful and I think it's a good looking watch to be honest.

A master watchmaker and an alchemist! Fascinating and throughly entertaining! Keep showing us your brilliant videos!!

Quartz or mechanical, the best watch is the one you own and can afford

Such a calming voice as you go about your work. This is an absolute treat to watch your videos. Thank you!

That kid is going to be supersmart when he grows up.

Posted literally 2 minutes ago and already a dislike. What a tool. I doubt they'd even watched the video. Keep posting the great vids!

I can't say if you are the best watchmaker, but you for sure make the best watchmaking videos.

I recently polished up an old Timex I pulled out of a bag of junk, and I must admit I love it as much as my swiss mechanical. It became unfashionable and its original batteries were never replaced, then spent decades in a sock drawer. When I booted it up, it was still under the impression it was 1971, hehe.

I am a retired senior I bought and sold antique pocket watches then wrist watches as a hobby for 30 years. I still love the watch business and enjoy watching your skill in bringing them back to life . Oscar Dekter Toronto Canada.

I'd love to see you do a side by side comparison of servicing an expensive quartz movement watch vs one you can buy for 5 quid in a supermarket or garage forecourt. I think it would make interesting viewing.. Anyone agree? Great vid. Your assistant is coming along nicely!

the patience and meticulousness of watchmakers deserve very special people

I dont know what I more like. The commentary! And something cool watching you expertly pull the watch apart and then clean and put it all back together! I subbed and see I have a great back catalogue to watch.

Another great video and your spot on about quartz watches. I have some very early Omega quartz watches which I bought as non-runners, have repaaired and they are very mechanical, superbly engineered and can be adjusted for increadible accuracy. One day soon I hope to share these via youtube. Keep the great videos and the cheeky humour coming.

The comedic relief you bring to these videos is brilliant! I absolutely love watching watch repair videos and when you add that touch of comedy, it makes it so much better. Now my wife is going to think I've gone mad when I start talking to the floaters in my eyes. 🤣

Thanks to these videos, I apply watchmaking precission to everything I do in life and I started seeing insanely good results. Idk if this is good or bad but others started calling me OCD freak when i suggest that the the tiles in the bathroom should be treated with steam exclusively and that the fossets should be shiny without chlorine residue from tap water.

Love this! I grew up in the Quartz Revolution in the seventies and remember how excited we all were about amazing accuracy and next to no maintenance plus greater resistance to shocks. As an adult with more spending power I have been able to collect some of the more higher end early quartz that I used to drool over so now have an early Seiko LCD , the famous first gen GP quartz amongst others. I also love the electric and tuning fork watches from back then as well as of course some vintage mechanical. Would love to see you service an electric and tuning fork watch!

you're slowly converting me into watch lover, my dad use to like them and i never understood why, and now i started to realise how classy of a man he was.

Nice to see a vid of restoring of Breitling aerospace, especially when you do the complete disassemble of the module to clean and repair it.

Thank you very much for this video and your comments about horologists starting out on quartz watches. I actually have three of them of which I am building up confidence to repair by watching your detailed and inspiring videos. One is a Casio that has a barometer in it, one is my original Timex Expedition, and one is a BMW M3 watch with a tachometer dial of which the stem is messed up.

Love the positive comment on the quartz system, I have had nothing but quality time pieces in quartz for along time now and none have let me down, currently sport a Sieko solar system watch..brilliant

Nekkid Quote: “ You have to break a few omelettes to make scrambled eggs right ” End Quote. Errr ok.

I have a Breitling B1 and Breitling Navitimer. I love them both equally. Fascinating video. Thank you.

I know nothing about watches. I am not a watchmaker’s apprentice, nor do I tinker, but I love watching you do the tinkering and I love your commentary.

Awesome how you interact with your boy! A true dad!

Bought a Lunar-Pilot HA Quartz a few months ago. I'm now back in love with quartz. So amazing to be able to set a watch and see it keep in sync day after day after day after...

No idea how I ended up here but I'm still patting myself on the back

All I can say is " You are the best watchmaker " out there ! Really enjoyed every bit of the video... Simply awesome job done with excellent perfection

What a transformation to the finished product. You made it look like new or gently-used compared to the condition in which it was received. Impressive.

I really enjoyed this. You show with perfect camera focus and masterfull editing the whole thing including the cleaning, taking the new things out of their packaging and involve your enthusiastic young helper in the paperwork. Brilliant!

When I want to look nice and fancy I wear my Omega Automatic Constellation Chronometer. When I really want to know the time I wear my $15 Casio. There's a place for everything... very nice video, thanks again.

First time here, what a brilliantly shot and edited vid. The no nonsense opinions and narration was an absolute pleasure that put a smile on my face.

As always, fantastic. The knowledge imparted is as much fun as the tear down. Seeing a quartz breakdown is very interesting!

I thought I was the bold one to detail strip a pistol of mine. this craft of yours is really amazing to witness, but never would I attempt it.

Love this channel. I have a "collection" of five watches I have owned through my 50 odd years. None of them special, and none of them work. It would be nice to get them all restored like this.

I have a 1965 Omega Seamaster self winder. Still working today, no battery, no problems! Might not be minute perfect, but, what the hell! What’s a minute or two a week. But, your skill is amazing! Well done, thanks for posting!

One can sure appreciate your Eyesight, dexterity, and patience. All of which I don't have so I'll just sit, watch and enjoy. .

You, AGAIN, brought joy to my day. Thanks neighbor. (fellow earthling)

This is so good, I’m gonna watch it again tomorrow! Nuff respect for appreciating that for most people, their first watches were quartz. As usual, the technical know-how on display is fascinating.

I am fast becoming addicted to your channel. I come from Rugeley, live in California now. No, not earning enough for the real deal watches. However. Santa and the universe brought me my first Longines. Conquest. I am looking at my first automatic I love the Tissot LE LOCLE POWERMATIC 80 20TH ANNIVERSARY. I prolly won't buy an automatic after this. Budget and humility. Love your voice. Like water over stones Brother. May the universe bestow many blessing upon you.

One of my favorite watches I have ever owned was from a company I don't think exists anymore. It was named Riviera, and it was the first watch I ever owned that wasnt a cheap 2 dollar watch. It had a square, gold dial and was mainly silver, with small gold accents on the watch band. It just kept ticking, and was always right on time. It kept going for almost 6 years without needing a battery. When I changed it, it kept stopping, and I was worried that because I couldnt find the company that made it anymore, I wouldnt be able to get it fixed. A few years passed, and i thought I had lost it. when I finally found and opened it up, i learned that it had a JP-01 quartz movement, one of the super cheap, easy to replace movements they make. That old friend is still in my collection as the watch that started my love for watches.

It is really a beautiful watch. After restoration it looks amazing.

I appreciate the Family Guy reference!

Played this video in the hopes that I fall asleep because of Nekkid's soothing voice. Ended up watching 5 other videos.

Complete Professionalism, with the exact amount of Humor. Luv it and Thank u!

I reckon the Nekkid Watchmaker could be an Olympic contender for playing "Operation"

You’re my favourite thing on the ‘tube. Love your work, man.

Loving the humour, it’s like listening to Ogmios School of Zen Watch Fixers. Only just started watching these vids, so addictive.

I'm sure if I was attempting one of these restorations my stress level would be off the charts but listening to you and watching is quite relaxing. Your videos can quite addictive, before you know it you've watched 2 hours of KZfaq.

I simply like your videos. Funnies and give a lot of visible infos about those beauties. Keep entertaining us please!

Wow, i never thought to see a repair on quartz movement! Well done sir! I am one who can appreciate quartz watches.

Very tenacious skills and patience required to be a watchmaker, microengineering is quite fascinating. Keep up the good work!

Outstanding! It was great having your son present with you!

I never appreciated quartz movement in my adulthood until this video. Thank you for reminding me the joy of owning one. I’m going to try and find my Casio calcuwatch at my parents house.

Fun to see a quartz being serviced!

Thanks for this video. I own one of these (BLG-Aspace128) superqrtz. Bought it in 2002, nearly 20 years old now. Still love the watch. Apart from a battery replacement every 3-5 yrs or so it has never let me down.

Another excellent watch repair and love listening to your ramblings. Looking forward to the next update

the 1st watch i did buy myself were a jeep quartz watch, its been through hell but i love it for being my 1st watch i bought 14 years ago:)

Wow-what a clever son you have. Must get this from his mother!

I have Quartz watches from the 70’s to the present and all are in great shape and keeping excellent time. I also have mechanical watches from Circa 1860’s to the present and love them all. Thanks for this video and educating all of us on the value of quartz watches.

Beautiful, did two of the original version 1 both marked Navitimer on the dial and of course with the small lower LCD panel. Replaced both LCDs and missing case screwed bezel markers. Nice style and extremely light on the wrist. Thanks for the video!

I was fascinated as a child by the technology of quartz watches and still hold them in the highest regard. I have small wrists and chunky, mechanical watches look ridiculous on me so I am grateful for slim quartz movements that are affordable.

I’ve no issue with quartz watches, but there’s nothing like the thrill of knowing that you’re wearing tiny hand made machine on your wrist, and that if you put it in a draw and forget about it for 20 years you can pick it up, give it a little shake or a wind and it will start working again

One of my favourites, good job 🙂. I like even the casios, they have their own specific movements and they deserve respect. I wear a PRT 300 now, tomorrow a seamaster, them a 007 and so on. I like both types of watches.

These kind of videos are very relaxing to watch. So a big thank you.

"Horology sheriffs" haha bravo.

when i was a child, i change myself the Casio Databank battery, the only time i send the watch to watch shop they put the rear case in bad position a miniature spring pops and shortcircuit , now ia have a dead Classic watch, on that time i explode on kid fury!!! i cant believe it, they are specialists.. but they do a damage, and not accept to repair it.. i never trust again , i do myself on all my watches.

Great video. I had an aerospace years ago. I had no idea they were as intricate inside as they are.

I love my aerospace… thanks for showing how to care for it. I am not an horologist but was fascinated by your video.

Haven't seen you for a while, love your show..

That was a pleasure to watch, I'm a huge fan of automatics, but seeing this neglected gem being restored was great!

I love this channel. Another great video. Love your sense of humour as well. May you live long and prosper.

A top story mate, I'm retired many yes now and was active when the Very first quartz came out. so simple compared with the accurtrons felt sorry for bulava because they had just go all the bugs out of there early models. Thanks for the video.

Absolutely amazing "restoration of Breitling Aerospace" God Bless and God Speed.

Parabéns, maravilhoso trabalho !!! Brazil, São Paulo.

The moments with your son are beautiful and priceless.

Thanks Nekkid, I adore your videos, despite having no interest in watch restorations. So therapeutic, and slightly tinted with a wonderful humour. Class!

I'm just here to hear your chat ... and admire your skills.

I have 4 Breitling SuperQuartz watches, including my 18 year old M1. They all get worn in rotation along with my automatic B01’s and B04, and are loved just as much 🙂 What do the sheriffs know 😆😆😆

Made me raise my eyebrows definitely....I will not be looking at Breitling quartz watches in the same light again....Very enjoyable watch.👏👏👏

I'm here for two reasons. 1) I own a Breitling. I have and love my Colt Ocean. I've had it for 29 years and she's been perfect. She looks as beautiful to me as the day my wife bought it for my birthday. I have small wrist and no, I don't fly planes but it's a Breitling! Reason # 2) You're videos are entertaining. My wife is no longer with me but I have fond memorizes every "time" I look for the "time" :)

A brilliant video, it seems a longtime between posts so I'm hoping to see more or your adventures soon please. Stay safe & take care

"Brass Acorns"...love it!

That’s a cool watch 😍! I’ve seen them many times but never thought twice about em. After seeing it in detail I kinda like it

Just relax and enjoy this amazing person and his art...Thank you so much!
