I had my 11630 MH overhauled last year - including fitting of a "fair" condition used Bezel i got through this forum. I didn't actually realise at the time that the bezels on Autavia's had an aluminium insert - I had wrongly assumed it was a single piece..

More recently aftermarket inserts have appeared on for sale ebay - distinguishable from the originals by the missing drilled dot at "12".

Anyway - it was only when examining the old badly pitted example with a lens many months ago I realised it was a removable part.. It is a really snug fit but sure enough the old insert popped out from the outer ring using a watchmakers screwdriver. I noticed yellowish traces of what looked like glue on the back of the original insert - so it may be an idea to put a couple of tiny drops of loctite or similar to retain a new part.

I think Jarl may have been talking about "popping" the insert out from the ring whilst in situ - which may be the most straightforward way to go about it. As far as I know the actual bezel ring has a retaining spring that holds it onto the front of the watch.

Anyway do let us know how you get on - as I'm sure this is something many Autavia owners might be interested in.. Also - if this is one of the aftermarket inserts you are fitting - maybe you could tell us how well it compares to the old original..
