Certina DS-2 Automatic

What I know is wrong with it

A serviced DS-2 automatic with a black dial in near-perfect condition. The case and crystal have been lapped rather than polished, so the grinding lines remain and the finish reads sharp rather than soft. Fitted with a balance wheel and a keyless-works spring from a donor movement; it now runs very well. The case is roughly 95% after the lapping, with a few small marks still visible. Waiting on a new strap before it goes up for sale.

No watch here has been pressure-tested. A period WATERPROOF or WATER RESISTANT stamp says nothing about the seals today, so treat every watch on this site as not water resistant.
