I've been wanting one for 20 years. When they came out ceramic/sapphire I did it.

As to accuracy, that's the rub. Not regulated, so it's a crap shoot. Pulling the whole affair out through the front makes regulation specialized.

Mine was 10+/day - no good.

Sent it off to Jack Alexyon, now it's 4+/day. It's capable of even better, but mailing it back, etc. is a PITA.

Rock solid at 4+, chronometer grade. 8L35 is no joke.

I have Strapcode oyster and jubilee for it, big improvement over the pin and collar OEM.

It's FAR more durable than I thought it would be, and I thought it was tough to begin with.

It competes for work watch duties with a King Turtle (ceramic/sapphire).

There's a blue version available now, Seiya has them. Might be a nice option.

ETA

It's made from GS parts - all of them - in the GS facility by GS technicians.

In all but label, it is a GS.
