GBOAC,
I like your watch but don't know anything about it.
What's the case thickness like? It does have lug holes?
What's the bezel construction like, have you pulled it and does it fit gen inserts?
Those are the kind of things I look for with Gmt's. really would be nice to find one that didn't need a ton of expert modding...like wouldn't it be great if TC made a Gmt in this series? The Bk put together sapphire Gmt using a certain explorer case looks to be the best way to go, barring a transformer Gmt..as far as sapphire Gmt's go.
