New Speedmaster 3861 issue issue

[eightball76]

So I managed to get one the early released Speedmaster (Hesalite) a couple of months back and after a few weeks it seemed to get a mechanical issue with the use of the Chrono movement. I rang the AD and explained my situation and was offered a replacement watch. It would take a couple of days for the watch to come to the store but they did have a Sapphire model there if I wanted to look at it. Well I saw it and I paid the difference as I already have a Hesalite 1861 so the sapphire would make a pleasant change.
Now my new one (sapphire) has the same issue after a couple of weeks. when using the Chrono, the second timer hand gets to circa 2 seconds and the whole watch seizes. I have to hit the chrono button again for the main (local time) second hand to start working and then I have to hit the chrono button again for the timer second had to start moving again. I have lost complete faith in the 3861 movement for now. I have contacted the AD to run through my options with the intention to get a full refund and hope to find out more later in the week. I love the watch but even if I get a replacement my confidence is lost. In the meantime all I can say so far is that the AD have been fantastic. I'm a little heartbroken to be fair as I really did love the watch.
