Don't let those unprofessional people touch your watch. I got a quote for a service of my perfectly working and watertight Tag Heuer (about $2000). When the watch got to Pollak, the price suddenly changed to 3 time the original quote. I told them just send my watch back to me. Next time in the shower - watch started to fog! To my horror I found out that the back lid was barely screwed in, so watch was not watertight anymore and probably ruined now (i'm now checking it with other, reputable shop). The reply I got from the shop - why would we make it watertight if we not paid for the job!!!
