Full service on a 2254.50

[KBM]

Hello, everyone!

I am in the process of buying a used 2254.50, the watch is in excelent condition, with the bracelet having been refinished recently to look like new.

However, the warraty card is dated July 2004 and the service history is unknown, so I assume it would be advisable to have a full service of the watch after purchase, since it is a 9 year old piece and it seems to be running a bit slow.

Having that in mind, how much should I expect to pay for a full service/overhaul of the watch from an independant watchmaker? (I will be in the US for about a week only, so I don't have time to send the watch to Omega).

I am very excited about this purchase, it is such an iconic watch! I was torn between this piece and a Seamaster 300, but looked hard at both and decided on the 2254.

Thanks in advance!
