I was one of those that thought I did not need a service movement.. let it rides til it dies, just enjoy it out of the box and worry about it later..
But crown winding was getting gridy, feels rough and movement rattles when you flick the wrist.. plan to do fraken project so thought I might as well do movement service with Mike...
Communication was great with Mike, Pm him here on rwi works best in my opinion. Crown winding now is smooth, very little rattles with movement , Mike even helped polishes off a ding on the case "very minor now"
Work done:
*GEN dial, hands, and crystal
*service movement 4130
*waterproofed, polished case
3 more fraken project coming ti Mike's shop
