Amazing video! What a nice pocket watch! and its movement is impressive, simple and robust... I hope Seiko makes an exact reissue of it... and that they don't make it as limited edition! :D

I just finished a mod on mine. What I've learned is that the bezel can be removed just like any other bezel (it has a retention spring) and then around the glass there are dimples so that you can unscrew the glass with regular case back opener.

after getting used to put it on my watches, I ordered another 5.

I have 2 Gen1's like this but in Gold. One of them says the time while the other says "It's" before saying the time?

Been doing some research on hydro mods now and the silicone oil version seems to indicate only quartz movements work over time. How's the viscosity for 3M Fluorinert and mechanical movements over time? Great video to find 4 years after posting.

Did you happen to remove the crystal and bezel? I'm wanting to build in a Heimdallr Ti 6105 case. I have not bought the case yet, but the chapter ring isn't really the right style for the SPB315 dial I have sitting here. Was hoping it was either SKX sized or some other common size. Thanks

Very nice watches, have you ever had a top hat crystal which has broken and needs to be replaced, the remaining broken crystal ring is still located in the watch case…

There is a Swiss company "Swiss hypertec" they produce these oilfilled watches.Have my hyperbar shark for more than 10 yrs now,for battery change you have to send it in to keep the 1200 bar resistance.They all have that bubble and also mention it in their description.

Thanks for the video, these 80-90s mid size Seiko divers look just so good

Where did you purchase the dial, because i have found one, but it is not yellow (bright) as yours ! Thanks

I just recently purchased a new old stock SKX011J1 Orange 🍊 boy . Absolutely loving it . Your yellow dial is stunning. In the past I had so many opportunities to buy this watch and didn’t but really wish I had .

Well, as a mechanical engineer, I have found it nearly impossible to source Fluorinert. Nowhere has it, let alone has it cheap. Mineral oil and silicone oil frequently work fine with most plastics and most rubbers. Why cant er get a watch designed with polymers that work with these? Baby oil gets rubbed onto babies, but we cant get it on our watches? Wrong material used there.

I wanna do kind of a similar project, where did u get the case for the watch?

Hi, any issues with hydro mod after all this time?

Pull case back and pull stem out as you would be setting the watch. Face down, vibrate and case as you tilt it to various small angles. Then refill what may have leaked out, over filling it. Just a suggestion. If you own a soniccare toothbrush. Maybe put it up against case while on, causing a high beat vibration, helping the bubble break up and move to the back of the open watch.

Mine goes off every half hour for the time. Do you know if there is a way to shut the automatic feature off?

Have you ever opened up an addiesdive diver 200m my-h3? I got a Seconds hand that does not hit the Marks. I was thinking of opening the watch and realign everything at the 12 o'clock.

Host bought my first ring watch. I have dozens of wrist watches pocket watches. Cheap and expensive. My latest favorite maker is Raketa. I own 3 worst watches by them now and my ring watch is on the way. Great quality company. Has been around for decades.

Hey there. Know it’s a long shot since it’s been a few years, but you mentioned you had put a Seiko vh31 movement in it before the mechanical movement. Was the vh31 an exact swap with the original movement?

A lot harder to put on than it seems. Just got and struggled. My problem was I didn't have very much tail end to pull. My wrists aren't very large either. I think 7.15-.25". The only thing that worked for me was to shimmy hard on the right side. The left side of the buckle (when facing) basically doesn't move for me at all. I just straightened it out on that side and back to the hard shimmy on the right.

I wear it exactly the same way. But if you look at the buckle logo it is up side down. I think that even from CNS are not sure how to put these on 😅.

Great video! Helped with my Addiesdive my-h6 puck style watch. I had just about given up on being able to open it. Thank you again!

I just received the MODERN PERFORATED WATCH BAND from them in brown and it looks great on my Sinn 356. I like it a lot. Wish they also included spring bars for them, that is the only ding I would give them.

Hi, does the dark chapter ring come out? And can you if you want to insert a skx007 chapter ring in ? Thanks

@thetimekeeper , Is the bezel turn when you installed the crystal? Thanks

Is it possible to replace this crystal with sapphire? How do I look up the right replacement crystal? (I have two Seikos and a Citizen EcoDrive with busted crystals.)

Has anybody put this on their SSK GMT?

End link (at watch lugs) on the SEII is wider than SEI which can be a problem for fit. This depends on the distance from a particular watch case to the end link spring pin and, depending on this distance, the end link can block against the watch case. The SEII comes with a rather wide end link spring pin. If the end link blocks against the case, a slightly smaller-in-diameter end link spring pin can allow full movement of the end link.

Just nabbed a Swiss made bulova ring. It’s awesome construction and when you pull out the movement it’s absolutely magnificent… needs work but runs! Has a lot of patina but it suits it 😊

Might get one tonite on Yahoo Jp.

Late to the party, Which Seiko is that? Looks Class

So, is there a way to fit a 28.5 mm std. dial in it? Thank you!

Where can I buy It?

I have one and it is a white face dial ... Great watch.....

one questions :) I am planning to make a hydro mod with silicon oil SEIKO PROSPEX SOLAR SNE569P1. Any advice?

Congratulations!

CAME WITH A METAL BAND, IVE A YELLOW AND RED FACE I GOT BACK THEN INMY COLLECTION

Hi, I have a Steeldive SD 1978 Emperor Tuna, and I want to change the dial. The SD 1978 should be open with the same method that you showed? Thanks in advance!!!!

😮

Is the polishing on that case a lacquer that keeps it from patenaing? Or did it end up getting patenad with time?

Wow, so much simpler than I had been told. I've read that you pull out the crown and fit an air hose to push out the crystal with air pressure. Your method is far less cool but much more sensible :)

Just ordered the same bracelet for my new Seiko SNJ027 Arnie directly from Strapcode after comparing it to the Hexad design. The complexity and beveled edges of the Super Engineer II convinced me . Awesome design, and nice job on video! Perhaps a comparison on bracelets would be interesting!

Any updates on the longevity of the hydro mod? Any leaking, fading, or excessive battery useage?

Is your friend still doing custom face dials? His insta page is down.

no uv epoxy necessary?

I just purchased the same model, and ordered three straps for this right away. Also planning to switch hardlex to sapphire. Just wondered if another bezel would look nice on this one. A bit too robust for an everyday watch. What do you think?

I have the same one. An amazing watch.💪💪💪

Is this highly collectable?

Stunning watch, what would this be worth?

I bought that watch 15 years ago for about $175.00 brand new, until now I have been wearing it and it works well! You cannot go wrong with Seikos!
