Question about removing crystal retaining ring on Clean GMT Master II V3

[JTB16635]

There are several ways to lower the gasket height. I place proper date mag as the top priority when fitting a gasket, then secondarily I try to achieve a proper (gen-like) crystal sitting height.

If you shave a 2.7mm to 2.6mm it will usually clear the second hand. Also sometimes you can carefully press the second hand down a little from where the factory placed it and use a 2.5mm.

Second hand catching on crystal

I'm using the Clark crystal and gasket. I had him send me (2) of each: 2.70, 2.85, 3.0. The Clean gasket in mine measured 3.0 When I tried the 2.7 the second hand stopped. So I installed the 2.85 and sanded it down a little at a time until it was slightly interfering with the second hand (drag). Then I installed the second 2.85 gasket and sanded it down so it was just a hair longer than the first one. Ordering extra gaskets is the way to go if you want to get it as low as possible without modding the pinions, imo. Walmart didn't have the fishing line I needed so ordered on Amazon and will be here Friday.

KJ2020, in the interest of clarity for myself you mention sanding the ID of the washer, are you sanding so it drops directly over the teeth on the retaining ring, or just enough so it still fits under the teeth, but can free wheel/rotate? My thinking is I'd still want the teeth to retain it but not impede it's ability to rotate. But I'll follow your recommendation.

The bezel tension ring (flat washer) should not touch the crystal retaining ring. there is a detent in the case that (should) define its width.
