Two things happened after watching this video: 1- subscribed; 2- Bought an AquisPro Date Calibre 400.

As a fellow watchmaker, this was very informative to me. You do very well with conveying information to people who may not be as educated as you. 👍

Absolutely amazing video. I'm so happy that a qualified watchmaker has taken such a big deep dive into the calibre 400. Most talk around this watch either ignores the movement issues entirely, or calls it an abomination. So a nice level headed exploration of the issues was very much appreciated. And I'm happy that it's something Oris could very easily fix with a revision.

I have owned this watch for about 5 month’s, I bought it in november 2020. The watch is beautiful and it is highly accurate. I didn’t bother about the minute hand jump because there is an easy work around and the watch is so accurate. But, there is a major flaw in this caliber that is never mentioned. I owned 2 copies of this watch and in both the caliber was replaced because of the same issue. My first copy worked fine for about 4 weeks, then I discovered that the rotor was blocked. The caliber was replaced by an new one which showed the same problem after 4 days! Then my dealer provided me with a brand new watch. This copy worked fine for again about 3-4 weeks, until the rotor blocked. The watch was sent to the factory and after a few weeks I got it back with a new caliber. This latest version again stopped after about 4 weeks. In the end I got my money back because I was fed up. According to my dealer Swiss watch makers never admit when they suffer from technical problems, but unofficial it’s admitted to me that I am not the only one. The problem is that the rotor in some occasions wiggles a little to much and gets stuck. It happens for example when you wipe your hands after washing them. The rotor always gets stuck in exactly the same position. I made videos from all occasions, which was good because I could prove I was right. In some occasions the rotor starts moving again, for example when you tick the watch against a wooden table or so. At this moment I can not recommend this caliber, I’m sorry. I would recommend to wait buying one, until Oris releases an updated version. You can still use the watch if you don’t mind winding it every few days, but that is not why you buy an automatic watch for daily use.

Would love to see this sort of analysis more often Possibly for Tudor's in-house calibers

I can’t believe it took me this long to find this channel. Great review. Thank you for taking the time to educate me. Looking forward to more of these reviews.

What a fantastic video! Jordan is extremely knowledgeable and well spoken, and has a perfect delivery for this type of analysis. Very well done.

Awesome job by the Master Watchmaker. Thoroughly enjoyed the format and explanation and expertise.

Thank you for this really interesting and brilliant video. That kind of content is a great addition to all the unboxing and design review content on KZfaq. Please go ahead and continue with that kind of sharp analysis of the inner life of watches. Greatings from Germany

A watch video that's actually informative, and not just advertising. I can't believe it.

It's super interesting to get a technical view under the hood from someone who repairs and maintains these wonderous micro-machines. Really well-done video!

This was fantastic. I also appreciate the opportunity to get to know Jordan a bit since he is putting together a couple of watches for me via Cincinnati Watch Company. Very nicely done.

Thank you for this ! I appreciate your point of view and technical knowledge

Enjoyed the caliber 400 deep dive. Appreciated the in depth explanation and opinions on the particular design features. Gladly subscribed and look foward to seeing more movements explored.

If you’re ‘into watches’ you should be ‘into technical videos’ of this nature. This gentleman’s insight, honesty and unbiased opinion matters. Well done. Thank you.

Absolutely fantastic, informative, eloquent , great explanations as to what’s going on and how relative things are in relation to items in the industry. Immediately subscribed. It’s always refreshing listening to a genuine expert 👏

Wow man thanks for your great review of this caliber! You deserve 100 times the subscribers!

Excellent discussion. Didn't think I would listen to the entire presentation but I was wrong. Very informative, interesting and insightful.

I’m glad I found this video, because of this I’m buying one.

I really like this style of video, so many other watch channels do not talk about the movements like this. Really good stuff, keep it up.

Very interesting and informative to see this detailed in depth overview from a watch makers perspective, awesome!

Great Video to explain the issue of the new caliber and how to fix it, thank you.

Oh man...so glad I found this video...i had not heard of this problem with setting the time on the cal 400...my oris cal 400 will be here Thursday and now I can set it correctly and precisely. Thanks alot!!

Extremely well explained. I really appreciate this presentation.

As someone with practically no technical knowledge about watch movements this was atill very interesting to watch.

Awesome review of this movement! Honest and very professional👍 Thank you!

Brilliant review. Much appreciated. Hope to see more in the future!

Thanks for the detailed and knowledgeable review. I’m going to be waiting for a revised 400 that winds more efficiently on the wrist.

Thanks so much for this video! Awesome to learn about the 400 movement 🙏

Excellent overview of this new Oris caliber! Thanks for the video.

Thank you for your easy-to-understand explanation, and the in-depth analysis on their innovation. Subscribed so I won’t miss similar content from you.

First time here and I just love that you explain the WHY about the technology! Very interesting! Thanks so much!

Thanks for the excellent overview and detail. I was “briefly” on the fence - had heard about the hand jump but quickly found this video. I ultimately purchased the watch just a few days ago. I find the hand jump situation to be a non issue. It is a design trait- somewhat charming even - it makes the movement imperfectly perfect in my opinion.

Thanks 🙏 ..! nice to see the issue from inside... giving a better understanding.

This video is great and thanks for providing such detailed explanation around how the minute jumping issue happened! Would have been better if there was a zoom in slow motion so that we could see a bit clearer on how the gear affects the minute hand. I just ordered my hodinkee diver 65 and can’t wait to play around with this new caliber 400

Superb review! Rich in details that only a watchmaker can talk about. Really a compelling video.

Jordan excellent video and assessment of the Oris 400 movement. Your knowledge and presentation are most appreciated for us watch lovers who wish to educate ourselves. Keep up he good work/videos!

Awesome video, in a world where a watch release is accompanied by 7 videos regurgitating the specs with some sexy B roll, this is very refreshing and valuable! As for Oris, I’m a big fan. I really like what they’re doing these days, true to themselves and genuinely interesting. Maybe they’re still finding their feet in the in house movement game but that’s fine by me, exciting things to come in the next few years I hope.

Thank you fort this outstanding Review!

amazing video. thank you for taking the time to make it :)

Great video. I love this channel!! I will still wait for 400 rev1.1, because calibers won't get the update till service 10yrs later.

Jordan, thank you for a well thought out and informative review. Subscribed 🙂

This is the first video I watched with you and I must admit I’m very impressed informative and interesting thank you very much

Very informative, thank you! I shared this with the Oris Watch Club Facebook group. Take care!

I wore a inexpensive but nonetheless well made 1st gen Invicta 9937 with the ETA 2824 for over 10 years. It also jumped if you didn’t relax the crown before pushing it in. This wasn’t a real issue and the watch itself was so accurate I could go months without having to reset it. Unfortunately, It was nicked from my carry on while rushing through airport security a few years ago. I never replaced it but I’m thinking this new Oris might be the one. Great video. It’s good to get a true experts point of view. Thanks !!

I really appreciate the way you explain the movement, how and why it works. I have subscribed to this channel educate myself. Thank you.

Great stuff, learnt something new about movements ;) . Looking forward to your next video. Keep it up.

Than you for the effort u put Into this video and for sharing your expertise!

Great and honest review of such caliber.

Wow, what a video. Me as amateur highly appreciates such stuff. Oris caliber 400 is very nice watch and I consider buying it. Have a great day.

Subscribed. Informative video, unlike those who don't know about watches and just only talking about watch appearance and common people hearsay. Well done. Keep it up.

Excellent information, thanks so much!

WOW ! Most excellent and informative review. Aquis 400 caliber is on my short list. Thank You.

Very informative and interesting video. Would love to see more videos with this guy.

BRILLIANT VIDEO !!! MANY CONGRATS TO YOU !!!

Subbed! I really enjoyed the discussion about silicon. Yes it's fascinating how human could make chips from silicon with such high precision for such low prices.

This is an awesome review! I'd love to see reviews of more movements like this.

Good job. Thank you for making this video.

Thank you for this brilliant, very informative video!

Great and honest review of such caliber. Alessandro Betti

I want to buy an Oris Aquis Cal 400, this video was very very very informative and makes me want to buy the watch even more. :) Let's hope they fix the jumping minute hand issue, but I'm already happy with the solution you bring.

outstanding review my friend!

Brilliant video, thank you!

Superb work Jordan

Great video with great information!

Great review. Thank you.

Great video. Thanks.

Great video, thanks!

A very interesting deep dive into the movement, thank you. Since I use a desk stand to place my watch on in order to do my job, I the poor auto wind efficiency puts me off for now. Putting things into context and understanding that all new movements have issues so soon enough Oris will I'm sure address these teething problems. Get it, teething problems...(giggling ensues)

Thank you for this review, very informative and very interesting.

thanks great review loved it

Wow so professional , so knowledgeable Thank you

Great presentation of an interesting "issue". Subscribed!

Just came across your channel and I love it.

You jumped to the top of my list of people I'd like to have lunch with.

I work both as salesperson but also as a watchmaker and this is a huge help to understand the mechanism and gives me confidence to recommend this watch to customers. I had hard time recommending this watch to customer since the issues you have addressed but now I’m confident to recommend this watch to those who want good divers watch. Thanks for the share!

Very intriguing video!

Thank you very much for this video, a balanced technical look a a new movement. Information was very well articulated so even I could understand it. A decision to design and implement a new movement is an expensive one to say the very least. This is impressive but not perfect as a lot of new products tend to be in those early stages. It's great to see that modern thought has gone into this with regard to cost and service as well, good DFM (design for manufacture). As for the lubrication? Maybe this is back stop should the silicon components wear a tad given this movement has a 10 year service and warranty, it would maybe run dry after some years anyway. The hand jump isn't an issue for me as I've always (not sure why, mechanical sympathy maybe) backed off the crown a little before pushing it home. A fix would be nice but ultimately with the crown back off does not affect the timekeeping.

오리스 무브먼트에 대하여 쉽게 이해할 수 있었습니다. 유익한 영상 감사합니다.

Outstanding job 👏👏👏

Really good review 👍 touched every point and well explained.

this is a gem, subscribed

Great video. Much needed, I would say, since they are many other channels that take care of the “other aspects” of the watch. I think you nailed it on this review. The caliber 400 has a lot of credit to it and it will get better over time. I haven’t have the opportunity to have one in my hand but I guess that moving the hands clockwise offers a higher resistance that produces an unintended amount of energy being stored while setting the time “going forward”. That produces the snap that we appreciate as a jump in the minute hand. Passing the intended time and bringing the minute hand backwards solves the issue because first, it releases the tension stored in the wheel and second, the drag going backwards is significantly less. Anyway, great movement, great watch and great review.

Thanks for an honest review, definitely subscribing to you

Thank you for this explanation of the the minute movement when the crown and stem is pulled.I was looking for a view of the keyless works and this was just what I needed.I think the teeth need to be straight cut wolf teeth and be better of with a plain intermediate gear style system.As you pointed out this has been worked out long ago with chronograph movements.I have venus 175 Valjour 7750 and Lemania 1341 chronograph movements that don’t have this problem.I would never buy an Oris watch with this movement because of that fault ( I deem it a fault) and am not a fan of Bobby pins that are used to secure the rotor.I have refitted rotors that have been knocked of ETA 2893 movements that have more purchase than on that sprung loaded rotor.I will be counted wrong if that securing clip passes the test of time.As always it is risky to putting a new calibre out and also risky being an early buyer of a new one.Thank you for the excellent review,I will be watching this calibre and hope it proves reliable for those who have put up with the Wiggles.

I have the watch and I do not get 5 days of power reserve. So, starting from no power, stopped, if I wind the watch about 20 turns, then wear it for say 8 to 10 hours, it may not be running by late morning the next day. As you mentioned, this is a problem for others as well. Thank you for your honest review.; you explained the issue.

Great analysis, thank you for it. It ist hard to understand wether Oris should detected the jumping minute hand during their test cycles and then fix it before delivering to the market?

this is a great channel

Genius. Thanks a lot!

굉장히 유익한 영상 감사합니다. 잘 봤어요!!

Brilliant video Jordan. Did you ever come up with a theory as to why there was lubrication applied to the silicon? In your opinion, would it make any difference to the performance of the movement if the silicone lubrication was omitted?

Great review. I am still very interested in, why they lubricate the escapement? I have seen it also done in Zenith silicon escapements.

Adjusted to 5 positions and some more to set the time some have found!

I think the time jump is ultimately going to find itself as an appealing quirk collectors will remember vexingly but also fondly about this watch.

That minute hand jump is absolutely inexcusable for a watch like this.

The Swiss Tech clone has more back lash in the gear set. It eliminates the problem of the hand jumping. You sacrifice that nice fitting gear set but eliminate an issue inexpensively. Otherwise the smaller gear would have to come away straight rather than on an angle as it does.

There is a 400-2 version out now. It would be great if you could test the winding with the new version.

Thank you.

Great video btw!

Need a slow-motion of the jump's minute part
