Here we have a gasket kit for the above SEIKO 6139 wrist watch.

Fits -

6138-0030

Included in the basic kit are -

1 x FH3180 Caseback seal
1 x DJ0160 Crown Seal
2 x DJ0060 Pusher Seals
1 x EC3360 Crystal Seal
1 x Silicone Grease Packet

Also note I now have various options for additions to the kit.

PLEASE DOUBLE CHECK YOU HAVE THE CORRECT CASEBACK ON YOUR WATCH AS SOME HAVE BEEN SWAPPED OVER THE YEARS. THERE IS VARIATION IN SEAL SIZES BETWEEN CASES.

PLEASE NOTE THS SEALS WILL NOT FIT AFTERMARKET PUSHERS AND SOME AFTERMARKET CROWNS. THESE PARTS ARE NOT MANUFACTURED TO THE CORRECT OEM SPECIFICATIONS AND OFTEN HAVE A GASKET GROOVE WHICH IS TOO SMALL TO FIT OEM SPEC PARTS.

THEY CAN BE MODIFIED IN A LATHE TO FIT, BUT THE SEALS WILL NOT FIT MANY OF THESE PARTS WITHOUT MODIFICATION. I WILL ASSUME YOU HAVE READ THIS DESCRIPTION.

My seal sets will pass a pressure test to the original specified depth rating of 70 meters. This is assuming they are installed correctly and there is no corrosion in the case.
