I really love my Wavecepter 430 (shares the most wrist time with my 5610) but I'm thinking about swapping the crystal.
To be fair it's still very good and I was happy to live with the tiny visible scratch that was present when I bought it, although looking at it with a loupe you'd think Torvill and Dean had spent their careers practising on it.
Another more visible scratch has appeared and it's beginning to bug me, so I'm thinking of getting a watch press and swapping to mineral...or perhaps even sapphire at the right price.
The original acrylic crystal has a pronounced dome and I quite like the 'lens' effect that kind of makes it look chunky, however it does lead to distorted reflections.
A flat crystal is perhaps a little more sophisticated and less likely to be scuffed or scratched.
I'm definitely erring toward flat - what would your preference be?
Also, I can't seem to find the precise diameter online (or anyone listing a direct replacement), so I guess I'll need a caliper gauge as well!
Never changed a crystal before, watched a few vids on Youtube but would appreciate any advice.
