Here's the difference between a really big Speedmaster... And a 125

For the sake of a fairly interesting for me, maybe not so much for you, video on watches, I broke out my two most peculiar speedmasters. The TV dial is big by any standard, The chunky case is obvious on the wrist but isn't too cumbersome to wear as a pseudo-daily wearer. The 125 is in entirely another orbit altogether. The super chunky modular case is more of a piece of aeronautical instrumentation cut from the dashboard of a World War I gunship fastened to links than to be loosely called a watch.
