I agree about the servicing costs. Many years back (34 to be precise) I was very lucky and came across a Sea Dweller that was going cheap, but it was in a state. It cost quite a lot to have it serviced and put right, but I thought was worth it at the time - then I sold in on about 9 years later after it started losing time, and at quite an alarming rate! (should have kept it though as it'd be worth a LOT of money now).
I've recently been looking at a nice 2nd hand Omega Speedmaster, a lovely looking thing, but then I looked into the servicing costs of around £300 - £400 every 4 or 5 years and I had to ask myself if I really needed to have that bill every so often? Eventually, the answer came back, no I didn't! There is always a temptation to own something beautiful & well put together, but like a couple of old flames from my youth, they cost a lot of money to keep going in the long run!
Now I make do with a good, reliable old banger that never lets me down. As for watches, well a tough, radio controlled, solar powered job is good enough for me. I don't need to try to impress anymore.
