How long have you had it and are there any general issue that you have noticed with operation or reliability. I've read stuff like "never use the Chrono" "don't hand-wind" it and 50% of all A7750 break. I want to weed out all of the noise and get info from someone who has direct experience.
From your picture, the date sheet looks good (not to far recessed like I have heard about with other watches) but did you notice anything else. It looks amazing, like it could pass for GEN. Do you know of any "tells" that would give you pause from wearing around someone who knows watches -- IWC in particular.
Do you give it a lot of wrist time, and how do you like it?
Ok, here we go
1) The A7750 is still garbage. Mine has an issue where if you run the chrono it loses alot of time (I ran chrono for 30 minutes and the watch lost 4 minutes). But outside of running the chrono it keeps great time at +5s/day. So don't run the chrono and you'll be fine.
2) Aesthetic wise it looks 10/10. I think it's classed as one of the super reps in the old NWBIG list (which is outdated). I haven't handled gen directly but I have seen gen and I could not tell the difference. I know the blue version has an issue with ZF where in some lighting it looks purple - which is why I went for black.
3) I would recommend getting the bracelet version. And then asking to get the rep leather strap as well (for the buckle). But the rep leather strap is horrible as per most rep straps. The rep bracelet is pretty nice and the on the fly adjustment works as per gen. The method to take out links is also per gen, although it's quite fiddly on the rep and it's recommended to go slow and gentle and not hard. You can pretty much break a link if you press the two buttons hrd.
4) The date is not recessed. This "sunken" date only occurs on non original configuration 7750s (so 7750s modified subdial layout). So don't worry about that.
5) Servicing, I know alot of watch makers won't touch the A7750. Honestly it may be better to swap to a gen ETA - although the caveat to this is you need to find gen hands or swap one of the pinions. The "seconds" hand on the rep doesn't fit the gen ETA or something. I don't remeber but there's threads about this.
I wear it occasionally, probably once or twice a month, it's not "large" but it is extremely thick due to the iron cage and 7750 automatic movement. It's a little heavy too.
Basically it's aesthetically 10/10. Movement is shoddy don't run the chrono. It's cheap at $350 so don't expect wonders either.
