Hi Joe,
Forget what it was last time... I think around 2 weeks?! I can let you know the turnaround time exactly tomorrow. I’m taking my Sherpa Guide MK1 for servicing, gaskets, pressure test and ultrasonic cleaning tomorrow.
Anyone that's looking for a good servicer in northeast of U.S. is Grand Central Watches right past track 38 in Grand Central Terminal, New York City, NY. The owner is very knowledgeable, mostly deals with vintage, has a clean room with filtration system and ideal environment for servicing...
