Ending the work week wearing my Daytona beater

The 5517 uses a Tropic 19, but I am not familiar with the case so others will need to provide those answers. In most cases, however, a gen tube/crown can be retrofit with little or no problem.

Ditto Nanuq. I would add that while a plexi xtal can scratch, most scratches can easily be buffed out. Also, sapphire is a fingerprint/grease magnet while you will rarely see any muck on plexi.

Yes & yes.

Still wearing the '41 today

Good point, but not an issue with the Acetimers, which are also silent as well.

Wore my 'Graph today But just switched to my '41 on the way out to dinner

No. I filter sinks & showers. Ideally, all incoming water should flow through a central reverse osmosis/UV filtration system, but since the problem, as I see it, is not severe, I am not sure that is cost-effective. But if you can rationalize the costs, a centralized system certainly would not hurt.

I switched over to filtered water (including for showering) 30 years ago as the issues relating to impurities within municipal drinking water have been known for decades. That said, I doubt there is any danger over the short term. But, long term, consuming these 'impurities' for more than 20 years is likely to have all sorts of consequences & none of them good. But since our air is similarly fouled, 1 can only do so much.

I only use the winders for my non-quick-set date watches & I do not use any of the large sleeves (remove them). My watches fit fine (7" wrist) with a bit of folded Kleenex between the clasp & pillow (which you cannot see)

I have had 2 Acetimers for a couple of years & run my gens, frankens & reps without any problems. My sole complaint is that I have not found their (or most other winders') watch guide to be sufficient to keep some watches' mainsprings fully wound. Instead, give each auto-wind watch 40 manual turns, set the Acetimer to its lowest number of turns/day & test the watch for a week or 2. If the watch stops, set the Acetimer to its next highest turns/day setting & retest. Use the lowest setting that keeps the watch running properly. Again, YOU must experiment with your winder to find the most efficient setting for your watch.

GC is semi-permanent, so it can be removed if needed & it will give you a bit more confidence, so I would probably do it. Just a couple of small dabs ought to do it.

Wow. It looks even better than I expected. Now, after seeing it with the black insert, I think you ought to give serious thought to minimizing that GMT hand.

The Rolex certification is extremely difficult, even for journeyman watchmakers, many of whom are not likely to make the grade. And I suspect that Alligoat's right about China being more than happy to step in to fill the void.

Oops. Sorry, I forgot that all the aftermarket GMT hands are made to fit gen movements & I had to manufacture the hand for my Phase 1 6542. I would still install the black insert when it arrives.

'42 2-day

What, no obligatory watch collection pics?

Rolex used left over parts from the 6542 on the initial runs of 1675s

Frank - It looks great. Have you considered replacing the GMT hand with a 6542-style 'small' point hand & a Yuki 7206 rivet or gen 6251H Jubilee bracelet? Or, to ice the cake, consider switching the insert to black. In that form, I think it would be very difficult to ID the watch as a rep.

In fact, I remember standing in my bedroom after returning from the local premier of 'A Hard Day's Night', holding the black & white promo pic of the group & yellow souvenir ticket (both of which I still have here somewhere), wondering if I would still remember these guys (the Beatles) when I was 40 (40, as a young teen, was about as far into the future as I could comprehend). As you probably recall, the prevailing wisdom was that the Beatles, like most pop acts back then, were a fad that would quickly fade & be replaced by the next fad.

Mods - RWG was hanging which caused triplicate post. Please delete.

It all depends on your particular case since there is a bit of case-to-case variation. In my experience, I would expect that it will NOT be a simple movement swap. In most cases, you will need to mod (grind/polish) the inside of the case to get the other movement to align/fit properly. But, again, whether or how much work would be required is impossible to say because of the variations in construction.
