Included in the kit are the following seals -
1 x 0K240B Crown Seal
1 x 0C3660B Bezel Seal
1 x 0C3060B Caseback Seal
The Vintage Time Australia Seal sets are an exact fit for this model and are based on the original specifications of the seals.
Please note these seal sets are designed to fit OEM pushers and crowns. Aftermarket parts may have fitting issues or require modification as they often aren't made to OEM spec.
Please also check the caseback has not been swapped before buying. This is a common issue with these watches and can make identification difficult.
Water resistance is guaranteed to the original specification (100m) as long as the seals are fitted correctly, the correct crystal is fitted and there is no corrosion in the case. (Tested on a Witschi ALC-2000 Pressure tester)
