Two thumbs WAAAAY up. Finally bought myself a 51-30 chrono last year, thinking about getting another one this year. REALLY like the tide, with the white face/black numbers, but they're tough to find
The 51-30 is a big watch, but if you're a big guy, it looks pretty normal, which works well for me. I seriously get complimented on it all the time. BEST watch without breaking the bank!
