Geday,
Based on the testing success of these gaskets they are available for sale. I really want to emphasise the appreciation I have for the guys that gave these a go and did the testing for me. Postage is free for WS members.
These are a new product and are made from a very heavy duty synthetic fluoropolymer elastomer, otherwise known as "Viton". The advantages of Viton over standard natural nitrile/buna rubber are the following -
- Better resistance to oxidants
- Better resistance to acids and oils
- Minimal deformation over time
- Minimal deformation while compressed (meaning an improved "snug" fit on the crown tube)
- Less mechanical wear over time
- Brown colour for identification
en.wikipedia.org/wiki/Viton
Because of this, Viton is an ideal and better material for crown gaskets. According to the paper specs, a Viton gasket should outlast the watch.
These crown gaskets have been pressure tested a number of times in 6309 cases and passed every time.
They are a proper metric gasket, so not loose and off-spec like the imperial ones floating around.
These come with the Vintage Time Australia branding and are an exact replacement for the original SEIKO part.
