If I were you, and I am reading between your lines, I would keep the watch. It seems you like it, you did not oberpay by a fortune, you know a bit of its history and you are not too keen on 100 % original parts.

Sum it up for yourself😊

Kind regards Max

Thank you, Max. I agree with everything you stated, except for being “not too keen on 100% original parts”. Given opinions differ somewhat on the Seamaster Chronostop being offered with a date function, I am hoping to gain additional info from forum members before making a final decision on returning the watch.

I strongly believe the dial is refinished. Also, the second hand is certainly not correct and painted red.

Thank you, @masteroftime. To make an informed decision, that this the type of feedback I am looking for. Based on the three thumbs up on your earlier post, it appears others agree.

@masteroftime, I am not at all disputing your position (and that of others). And sincerely appreciate your time and input. However, I am hoping you might be willing to invest a little more time towards a layman’s education.

What are you seeing that has you confident the dial is refinished?

I am in @masteroftime s boat, the Seamaster part of the dial looks different to most of the dials you find on the net. Especially the „r“. Also the capital letter „S“.

kind regards Max

Agree, Max. The difference really jumps out when compared to the high-resolution examples of the Seamaster Chronographs shown in Ashley Budgen’s Part 3: https://stories.omegaforums.net/chronostop-part-3-145-007-145-008/

Additionally, the Omega and Chronostop symbol/text do not match up with the example in Ms. Budgen’s Part 1:

I noticed this as well, but thought it might be an artifact of the photography

I agree with everything you stated, except for being “not too keen on 100% original parts”.

I’ll admit right from the start that I’m in the minority of forum members, but I just can’t get worked up over the provenance of watch parts. Either Singer (or some other supplier) painted the dial for Omega, or a third party repainted the dial for one of its customers. Since you like the watch, the quality—whatever the source—is high enough to give you pleasure. Were I in your situation, I’d keep the watch and enjoy it.

Maybe ask yourself which outcome you’re likely to regret more a year from now: passing up the chance to own this particular watch, or keeping the watch but living with lingering doubts about its originality. Also keep in mind that there are plenty of other Seamaster Chronostops, including one currently available in the private sales forum of this very site.

Agree with above. I don't know this reference but people above who do think this is a repainted dial. I understand this is frustrating OP as you came asking about the strap. But arguing with the opinions is confirmation bias, choosing to believe what you want to believe, and this will probably bug you over time. So maybe its better to return it and look for an original example, as @sathomasga says above there are more chronostops in the sea. I think that is what I would do anyway. Good luck with whatever you choose, and welcome to OP.

All fair, beneficial and appropriate points. With everyone’s help and input, I now have reasonable and defendable confidence in what I actually have. Thus in a much better position to determine next steps. I sincerely appreciate that!

Thanks again to everyone that took the time to weigh in and contribute to my much needed education. I sincerely appreciate that! For the benefit of the next potential rube, like me; recapping the lesson and making sure I passed the new forum member aptitude test:

Documentation and Resources

• Omega sales and marketing publications of the period show the Geneve Chronostop available with the Calibre 920 date function and rotated orientation dial, but not on the Seamaster Chronostop.
• Multiple authoritative articles on the Geneve and Seamaster Chronostops have been published:

https://stories.omegaforums.net/chronostop-part-1-geneve-chronostop-rare-japanese-variants/

https://stories.omegaforums.net/chronostop-part-3-145-007-145-008/

http://www.old-omegas.com/chronostop.html

Transplant?

• Ashley Budgen’s “Chronostop Part 3 - Seamaster Fixed and Rotating Bezel Variants” specifically states: “The Seamaster Chronostop only comes in one dial, and accordingly only in one movement across both references (145.007 and 145.008), the Calibre 865”.
• The Geneve Chronostop dial and 146.010 Calibre 920 movement are sized so they physically could, without difficulty, be transplanted in a Seamaster case with outer Seamaster bezel.
• The Seamaster Chronostops were purpose-configured as is evident in the Omega sales brochures. The subject watch has a 24-hour outer bezel, which allows a pilot to monitor two different time zones. Additionally, it has a 90° rotated orientation dial designed for drivers. A pilot would not need a rotated orientation dial. A driver would not benefit from a 24-hour bezel. Therefore, it seems very unlikely Omega would offer this dial combination.

Redial?

• The print and script on the subject watch dial is unique and clearly different than dozens of Seamaster Chronostop high resolution photography examples readily available on the internet, as well as in the aforementioned published articles.

Additional Observations

• Additionally, the second hand has clearly been painted (red when it should be orange) and the case has been polished. The type of crystal appears to be domed, not tapered and flat like the original. Those modifications indicate the watch has a history of cosmetic adjustments.

Conclusion

• The evidence strongly points to the conclusion that the subject watch is a Seamaster case, transplanted 146.010 Geneve Calibre 920 movement, and older refinished, patinated Geneve Chronostop dial with forged Seamaster script.

It may be worth changing the title of the thread or creating a new one to get more experts opinions.

I’ve recently picked up a 145.009 and did a lot of research. I physically picked up my watch from a vintage watch dealer and one of the topics we discussed was how there’s a growing number of watches that are the 09 variant but have had the dials rotated to look like the .10 variant as these command more money even though the dial feet don’t fit the case correctly. It looks like your watch could be a similar example although I’ve never seen this tried with a 145.008

Here’s a good visual ref

Edit: just realised from your pictures that you have a date window so not sure where that dial was sourced from

Thanks @Bernardino. Great suggestions. Being new to the forum, I need to figure out how to make the changes you recommend. However, your visual put me on another great reference. With my previous list, I should have included “Omega Chronostop Reference Guide - The Monopusher Chronograph” by Marcus Siems: https://goldammer.me/blogs/articles/omega-chronostop-reference-guide

you're probably best creating another thread and adding a link to this one for background info

not sure if you have the correct tools or are close to watchmaker who can remove the case back and confirm what's inside as this may help determine what has been done to your watch.
