Service will be required as it froze about 20 minutes later. Shards have fallen straight down and are either locking hands together or worse have gone through the dial hole in to the movement.If it's any consolation, I've done that to a gen before, lol (Speedmaster, not Explorer).
One of the reasons I prefer acrylic to sapphire crystals. I use tool watches as intended, and doing that to a sapphire crystal usually means a full service is required.
To an acrylic crystal, it's a quick and relatively cheap repair...
It's a nice movement so I'll do a partial if not total service when I get the new glass. For now - it's dial down on the top shelf with the crown pulled out and hacked.
Oh well, it's all experience - and you know what they say about experience? - it's cheaply bought at any price.
