Just came across this thread...
Here's my 1938 Rolex Oyster. The first waterproof watch.
My Grandad bought it new in 1938 and then my Dad used it and I inherited it in 2004.
The first thing I had done was had it cleaned and serviced at Rolex London at the cost of £500. I also had the glass replaced as my Dad cracked it about 20 years before I got.

Then about 3 years after that I cracked it. I wear it pretty much every day, so it had some use.

As you can see our family has fairly acidic sweat by the corrosion

I bought the strap earlier this year as the metal elesticated strap my Dad had bought finally gave up. I couldn't get an original one (no surprise) so I just bought nice ostrich leather one
it loses about 1 minute a day at the mo, but it just needs a service as I haven't had it done for 20 years.
