The Globemaster GMT is made with a particularly interesting modified ETA 2836 movement offering both an independently adjustable GMT hand while retaining a "jump hour" functionality. It's based on ETA's day-date movement with the day becoming the 24-hour hand. It's amazing. I've never seen anything like it. The 3-6-9-style on the face is simple and classic, while retaining a utilitarian, "gadget" feel through the hash-marks and very unique skeletonized GMT hand. The buttery yellow GMT and seconds hands add a minor shock of color. The small, unmagnified date at 4 o'clock also lends to functionality while not cluttering the face. The entire face (indices, main hands) is illuminated, which glowed in some respect for a 4-5 hours after a 5-minute charge in direct light. It is water-resistant to 200 meters, as is the base standard for any dive watch.
Part of the reason I love Omega is that my father gave me his 1950's Omega Tank watch, so I've always felt a fondness for the brand. It represents so much more than just a brand, as my father loved this watch and passed it on to me.
