MKII watches are excellent. Bill Yao really takes the trouble when designing and producing them. I've had 2 in the past and I really couldn't fault them in anyway.
The MKII Blackwater was designed with the Benrus Type I in mind. Clear and legible dial in an asymmetric case. Bead blasted. Sapphire crystal. Truly excellent. I regret selling mine:


Also had the Stingray which pays hommage to the Blancpain Fifty Fathom. What a wonderful watch. Really chunky with great wrist presence. I sold it at a point when I had too many dive watches in the collection. And how I've regretted ever since!



All in all, I would not hesitate to recommend Bill's watches. There are a few more on the pipeline but prices have gone up as well. I suppose that's the only downside to it.
