...especially the first generation pieces (including the MCM). The Master Compressors are a functional 41.5mm with reasonable thickness, yet they still have good wrist presence for those to whom that's important. The compressor keys are very convenient, much more so than wind down crowns. And the watches look like nothing else out there (yet still look good!). Unlike so many other sport watches, the Master Compressors aren't derivatives of the Rolex Submariner or the Royal Oak et al. I sure love mine...
Cheers,
