Lovely 
One of the watches I miss the most that I sold. Solid like a lump of rock
Possibly worth mentioning that the bezel is Tegimented (i.e. hardened to ~1500 Vickers), just not the body. Since the bezel is always most vulnerable, it’s a bloody useful feature on a fab watch.
If I didn’t have both a U1 and T1 I’d be on it - especially as it’s a more wearable size than either
