As always a QUALITY job from Duncan and a watch to be proud of Matt
cannop said:Hi Matt,
I've now fitted the crystal and pressure tested the watch to 30bar, which it passed successfully you'll be pleased to hear!
Here's how it went, the shroud and bezel removed
The crystal locking ring removed
The old crystal and nylon slip ring removed
A windowless watch
The new crystal, slip ring and locking ring refitted
In the chamber for a leak test, up to pressure
Wait 15 minutes and submerge
Release the pressure and no stream of bubbles so it's fit for the 30bar test in the hydrostatic tester
In the chamber
Lid on and up to pressure
Wait a few minutes and look for a large pressure drop, the pressure always drops a little but that more due to the seals in my tester rather than the seals in your watch!
Out she comes
Onto the warming plate
Let it warm through then place a cold droplet of water on the crystal. If there was any moisture ingress the crystal would fog up where the cold spot is. Needless to say yours was fine.
While the pressure testing was going on I ultrasonically cleaned the bezel and shroud components. The bezel isn't loose like a lot of older tunas, it feels just right to me after cleaning and slicone greasing the o-ring - firm but not tight.
The watch reassembled
Without sounding like a one man Duncan fan club I just just wanted to post this thread to say thanks for making my beloved Tuna even more special. If you don't already know Duncan and need any work doing take this as an A* recommendation.
I'll post a live pic tomorrow when it's back on my wrist.
Haha - to says its never going diving I think I can live with 32Boo should've tested the Tuna to 100BAR and not 32.9BAR imo.
That was my bad Bry, I'd just tested a 300m Ecozilla and had it in my head that this was a 30bar test too.Boo should've tested the Tuna to 100BAR and not 32.9BAR imo.
Would you happen to have pics of an Ecozilla disassembly and testing, Duncan?That was my bad Bry, I'd just tested a 300m Ecozilla and had it in my head that this was a 30bar test too.
I know! :icon_scratch:
