Beasties from the nineties compare! While X-33 is specified bigger, 42.25 vs 40mm, and definitely wears bigger than the EZM1, if you ignore the X-33's 9 o'clock bump and just measure the bezel ODs, they're practically the same at 40.7(X-33) and 41.0(EZM1).
The X-33, which is no thin watch at 14.4mm, is actually 2.2mm thinner! Both are within a few grams of each other at 108g(X-33) vs 101g(EZM1) on their Ti bracelets. YaY!
Going X-33 today! (Sorry, the UTC time is some random nonsense time, but the days into the year is correct...woohoo!)
