Haven’t had my hands on a C case Constellation for years, then like buses two come at once!
Both of these watches were good examples, the steel one has a very original case with well- defined edges, I did nothing cosmetic but replaced the glass, crown seal, caseback seal and mainspring. Fortunately the spring barrel, reverser and rotor bush were good for further service, they’re the bits that often need replacement and they’re not cheap.
The gold one had clearly had an encounter with a polishing wheel, with very little of the correct brushed finish in evidence. The polishing had been done recently because the watch had no damage/scratches. Refinishing gold-capped watches has to be done carefully, there’s a decent layer of gold compared to plating but only around 200 microns from new. I managed to apply the correct brushed finish with contrasting polished edges, same treatment for the bezel, and the watch was transformed. A replacement sapphire crystal, full service of the movement, replacement crown and caseback seal, the watch is now back to full health and looking as it should.
One big advantage with both watches is the condition of the dials and hands, that’s v. important when buying and it’s worth paying a premium for.
Had a nice steel C case myself on original bracelet several years ago, sold it and wish I hadn’t!
