The thickness of these caliber-9300 powered Speedmasters was and still is an often-heard complaint. These watches were slightly smaller in diameter than the Speedmaster Professional, but at 16.17mm thick, they were also quite a bit beefier. They were equipped with the in-house-developed automatic caliber 9300 housed in a 41.5mm case. Omega also brought it back in 2017 for the 60th anniversary of the Speedmaster.īut wait, there’s more! Back in 2013, Omega introduced a new series of Speedmaster ’57 watches. It saw a brief revival in the late 1990s, making it one of the first Speedmaster re-editions. The original was Speedmaster with a steel bezel, straight lugs, broad arrow hands, and the hand-wound Lémania-based movement.Ī short-lived model, it was only in production from 1957 to 1959. The Speedmaster ’57 is a nod to that first chronograph with an external tachymeter bezel, the reference CK2915. Today, however, we’re looking at the latest Speedmaster ’57 in blue.

Whereas the first variations were indicated with Mark 2, 3, 4, or 5 (and even 4.5), later on, we saw Speedmaster Day-Dates, Speedmaster Moonphase watches, and even a (very limited) Speedmaster Perpetual Calendar for the Japanese market. However, other Speedmaster variations are available, and this has always been the case since 1969. For the diehards, there’s probably only one Speedmaster - the Moonwatch.
