You are indeed a lucky man. This looks like an excellent foundation for modding. Here's my rating:
No.1 the thick crystal is perfect. Look how high it sits above the bezel. That's good and rare. I doubt if TW Best of MBW is even this good looking. Look at the gen's crystal. Yours just as good. That's rare.
No.2 the date mag is OK. It could be a little large because of the photography. But look at this gen. Doesn't it look about the same mag as yours? If your's off, it's only very slightly. I won't do a thing about the date mag. The date font might be a little too bold. If it bothers you, put a noobmariner datewheel overlay on it. $10.
No.3 the CGs are fat but it means there's a lot of metal to work with to get it down to the right shape. One modern sub rep has certain parts of the CGS too thin and there's no way to get them right whatsover.
No.4 the rehaut is not deep enough but decent and not too conical. Nothing you can do, nothing to worry either.
No.5 the bezel teeth too angled down, get a better one when you have a chance. Not very noticeable. A better one will make it look more handsome. That's all.
No.6 bezel insert is not good enough on any sub rep. So get a better one from Palp or Joe or the cheap Jewelery Tools insert ($15 shipped)
No.7 dial is ok but can use a noobmariner dial. $8 only.
No.8 SELs of the bracelet are too long. They should be shorter than the lugs, totally inside the lugs.
No.9 crown is low on the case when viewed from the side. It should be higher. Look at the gen's crown in relation to the bezel. Nothing you can do about that. It's a common problem with all sub reps. The best in this department is the noobmariner, followed by TW Best and MBW.
Don't give it up because it's $36. It's an excellent foundation next to the TW Best or MBW which are what 10 times more?
