Where to begin with the Omega 321 movement? Perhaps one of the most iconic movements of the 20th century, the 321 (3 registers) alongside the 320 (2 registers), was made in a time when quality really mattered. The column wheel caliber 321, developed by Lemania and used extensively by Omega in the ’60s still remains as one of the most reliable and quality movements ever produced. In fact, it is so revered that Omega recently re-released the caliber in a modern watch- the 105.003 Ed White reissue. That says a lot.

This example is a Ref. 145.005. Produced in 1967 and housed in a 35mm stainless screw back case, this is a really special watch. While it is relatively easy to find Omega dress chronographs, to find one in such excellent condition is not easy. The case is super sharp, with its original dial and signed crystal not something you see every day.  While the watch may look simple and ordinary, it is a perfectly designed, well proportioned, and timeless watch that will suit any occasion.
