My two month old Marine Diver has stopped twice and I sent it in to UN for evaluation and repair. Even when it was brand new I noticed that the sweep of the second hand was not smooth. Though it went around in sixty seconds, there were intervals of acceleration and deceleration. Based on what I've read here, in prior postings, it seems like the two problems are related. Will this be easy or difficult to repair? Will the problem be definitively solved or will it likely occur again? Of course, being without a new watch for an estimated 6-8 weeks is a bummer. Any input would be most appreciated. Thank you.
