You can send your Omega watch to Swatch Group to do checking, they will tell you the condition of your watch, for a watch take about 45 minutes to 1 hour & charges is around RM31.80 only, they will print out a report in A4 papper, you can search the location at goggle and also with the price for full service for different country different charges. I just send my 2 Omega on last 2 weeks & just watches without warranty card.
