This is why I value warranty. A few hours ago while my Speedmaster BSotM was just sitting dial up on my desk, it just stopped. Made sure it was fully wound (could hear clicks of clutch slipping) but balance wheel just doesn't move. Pulled out the crown fully out then in a few times and the balance wheel wobbled for 1-2 seconds each time but nothing. It has been my daily wearer for the past 2 years and been very accurate, +/- 1 sec per day depending on position. Will have to drop it off at the boutique when I have time so will strap on the X-33 again while it's in service.
