Dear Omega customer service,

I recently decided to take my Omega Seamaster Professional (2531.80.00) to the Omega service center in Bangkok for a service.

I explained that the watch was running 7 seconds slow per day. They offered to inspect the watch, regulate it and advise me as to whether a service was needed. It was explained to me that the watch could not be further regulated and was running slowly because it was ‘dirty’ and ‘in need of lubrication’. I was advised that a full service was required. I decided to think about it.

I was surprised to find that my Omega was now running 10 seconds slow per day over the next few days. This seemed strange and so I decided to buy the tools required to open my Omega (a genuine case holder and opener).

Having opened the case I discovered that my watch seemed to have been regulated to run slowly. The regulator adjustment screw was turned to half a click slower than the middle setting. I moved the screw to one click faster than the middle setting and re-cased it (it is now running consistently 1 second slow per day). The movement was exceptionally clean and showed signs of lubrication on all visible pivots and jewels.

I subsequently tested the watch in each of the five positions proscribed by COSC (dial up, dial down, crown up, crown down, crown left) over the course of 5 x 24 hour periods. Accuracy was measured against the atomic clock. I discovered that the watch is running well within COSC specifications.

As you might imagine, this experience has greatly shaken my confidence in Omega servicing. I would be grateful for an explanation.

Sincerely
