As we all know the new SH4131 movement is now available in the latest C Factory Daytonas and thanks to both C Factory and our dealer @CTime I was sent the very first one off the line for testing and evaluation. Now, there are far more experienced Daytona experts than I discussing the sub-millimetre accuracy of both the rep and the movement so I'll just say that the fit and finish, to my eyes, is superb with nice edges, brushing and polishing so what am I going to do?


I'm not big on the looks of the movement, it's a closed case back after all but what I do care about is how well it's made, will it (and the watch as a whole) take daily wear and a bit of abuse? CF's latest GMT has just come off some four months of use as my daily and it has stood up very well indeed. It's been worn to (and into) housefires, road crash rescues, wildland fires and more. It's been worn wrenching on cars, drowned in engine oil, it's had spray paint on it and cleaned with thinners. It's been cleaned with a toothbrush and dishwashing liquid in hot water and even worn while operating a jackhammer to break up a concrete slab. The GMT has come thru all of that with flying colours while maintaining accuracy within 20 seconds a week.

Now, we'll find out if the new Daytonas are as solid as the GMT because I'm going to beat the crap out of it for three months at least and report back here when it's done and dusted.
The movement in question




The watch on the timegrapher. A lot of the "noise" on the screen is due to the MTG-5000 preferring a naked movement to a cased one (even with the case back off) but I didn't wish to decase the movement at this point.


Two print traces from CH and H12 positions.




We will see how things compare after a few months of beating the hell out of it so watch this space and we'll see how both the watch and the movement cope with being used and abused in a manner that few if any of you would treat a Daytona in. Hell, I doubt many of you would treat a GMT the way I do 😁
What do I expect? Based on the way the GMT held up I expect good things even of the far more complicated chrono movement and I expect the watch itself to take everything I dish out to it. Let's find out if I'm right.

Thank you boss for taking the time and smashing around those watches for us;)
see you here in 3 months
PS: Do you have any pictures about the GMT AFTER surviving those things you did somewhere? Maybe I missed them, but would love to see them @trailboss99
:D

@trailboss99 Interesting to have an insight into your typical day.

Are you perhaps hiring another person for this test? I'll be happy to test one of these beauties :ROFLMAO: Looking forward to the final verdict 👌

It's been off my wrist for 24 hours, I'll get some pics and some timegrapher results ASAP. Suffice to say, it backs my belief that a lot of vintage builders vastly over age the pieces they build. On that note, I should take some pics of my 1680 which was my daily for around 5 years and had a similar life.

Fire rescues, jackhammers, engine oil, spray paint and thinners. Just wow. A day in the life of our @trailboss99 Respect. You can’t ask for more real-world torture test conditions than this. It’s reassuring my DD GMT is as solid as it is pretty. Thank you for field testing our SH4131.

If I get a smudge or water droplet on my pieces, I need to clean them asap 😁

Mess around with the chrono features like a child or someone who has never seen anything like it before. Give it hell. Thanks for doing this for us.

Good luck. Beat the shit out of it!
