Omega Seamaster Cosmic 166.026

Omega Seamaster introduced Ref. 166.026 in 1967. The model features a uni-shell case with the body made from a single piece of stainless steel – a robust method of construction that reduced the risk of dirt and moisture entering the watch. This example of the model features a satin finished dial.

Powered by the excellent Omega automatic calibre 565 the movement has provision for fast date change. The date changes automatically each day at midnight but can be manually advanced when required by pulling the crown out to its second setting.
