beautiful watch!

everything looks perfect but with the crown that does not close properly until the end, how can this issue be fixed?

Seems inconsistent as mine closes perfectly. Maybe the crown tube can be fitted a bit tighter to the case as this governs how far the crown screws in.

It’s fine on mine too. I hadn’t screwed the crown in all the way prior to taking the pictures.

are you sure for that? because many members have pointed this out as a small issue.
I also have a vrf with this problem

The crown shouldn't screw down completely flush, it should screw onto the gasket. If it's stopped metal on metal then it's probably going to let in water.

Correct, there should always be a slight gap but some earlier ZF were too big. Here is mine close up which I feel is as exactly as it should be.

In which case your crown gaskets are probably shot from over tightening. Triplocks shouldn’t touch the case when screwed in whether it be Subs or GMT’s.

I’ve just stripped down the whole watch this afternoon(lockdown boredom) and popped everything in the ultrasonic cleaner and stripped the bezel and re-polished the sharp edges off the bezel teeth and put everything back together.
One observation though was the insert does not have the ‘clean’ engraving on the back like usual. Have to say though that the numbers really do pop after a clean!
Have to compliment ZF on the machining of the parts though, excellent fit and finish to everything. A few pics below.

no i have never over-tightened any of my rolex i had. the crown must close normally until the end without a gap. I'm absolutely sure of that

Show us a pic of it then. You can look at many images and the crown should never touch the case. I’m not going by images by the way. I buy, restore and resell watches so I’ve handled many gens over the years but not taken any work during lockdown.

What did you use to sand the bezel edges, Micro-mesh w/ oil?

I was expecting a better shot of the gmt but it does look to have the Rolex gap.
The crown does look like it doesn’t screw in far enough on the vrf. It’s the only version I’ve not owned so can’t comment on it really.

i don’t have my gmt right now, but the crown close properly almost until the case.

vrf gap is big. so.. on ZF is not so bad?

The gap on my ZF is good but some seem larger. I guess it’s a personal choice if it bothers you or not.

Received my LN today. Approved the QC on the 15th and it arrived this morning. It's my first sub and it was strange seeing it in the flesh - looked so small at first after pouring over so many macro pictures on here. Makes you realise how imperceptible some of the issues are when it's on the wrist.
