Master Ultra Thin 34mm Variations?
Sep 21, 2016,04:47 AM
I've been researching and pondering this for a while, it seems there are two variations of the original MUT (34mm with caliber 849), an earlier one which has the solid caseback and a later one (more commonly seen) with a sapphire caseback. Both reference numbers seem identical (145.8.79)
Does anyone know which year this transition is made and whether there may also be solid caseback MUTs with caliber 839 instead of 839? I've attached two photos for reference.
Thanks!

Mine is the steel Master Black from the late 1990s, so I can can offer a caliper-verified measurement of the 145.8.79s with display-caseback tomorrow. My understanding always has been that the display caseback added 1mm to the thickness of the solid-back ...
