Based on the scope reading, the movement requires cleaning/oiling &/or the balance is weak, which could be due to the mainspring being insufficiently charged.

Wearing my 16014 today

Sorry, I do not know the tap size/dimensions (I use the Rolex taps, which are unmarked), but I can tell you that if the bottom of the gen tube is beveled (as opposed to flat), the case hole should be countersunk. Click me

Use Firefox. Why are you still using IE anyway?

Ditto.

Nice score. This is exactly the type of place where I sourced some of the NOS parts for my Phase II '42. There is alot of old Rolex stuff sitting on old watchmakers' shelves.

Ranked in order of bezel/case accuracy - gen, Minh, Phong, NDtrading, Yuki (you will need to research their current web links as I do not have them).

Looks like GMT is bottom of stack

Upped the bar again.

Mystery today

Looks like aftermarket/new production.

Brevet, which means patent, was engraved on early production runs of certain models that contain patent-pending features. In addition to the case engraving, the crown would also contain the standard brevet +. The earliest 6542s would have the brevet marks while normal production (most) did not.

I wore the 6536-1 today

Ending the work week still wearing 1 of my DJs

Please do not repost an entire set of pics just to add a line or 2 below.

Similar, but the Quad 4 Acetimers have a lifting tab (located on the front of the top cover, just above the lock) & spots for 5 idle watches in front.

I have a few Acetimers that have worked flawlessly for several years. They are quiet, operate on either A/C or batteries, have multiple speeds (to suit different watches' winding requirements) and look great

Rolex, by far. Excellent fit/finish with sufficient spring tension to keep the pins extended into the lugs, which has been a problem with all aftermarket 'bars in my experience (including all mentioned above).

Interesting.
