Description
The Omega Speedmaster Perpetual Calendar is a limited edition of 50 pieces created for the Japanese market in 1991, honoring the 700th anniversary of Switzerland. It is powered by caliber 1160, which is housed in a yellow gold case of 39mm. It was available with either a yellow gold bracelet or a brown alligator strap; though the main image is supplied by Omega, it is believed that this strap is not original.
Movement
Omega caliber 1160 is a self-winding caliber. The base movement is the ETA 2892-A2, which is fitted with a module for the perpetual calendar and chronograph.
