The Seamaster Planet Ocean 45.50 mm Chronograph, calibre 9300/9301
The Seamaster Planet Ocean 45.50 mm Chronograph is equipped with the exclusive OMEGA Co-Axial calibre 9300/9301, the first in our family of in-house movements to incorporate a chronograph function.
The featured models have a bold 45.50 mm stainless steel case with a choice of bezels offered either in orange matt aluminium or matt black ceramic. They have matt black dials.
The featured models are presented on a brushed and polished stainless steel bracelet with OMEGA’s patented screw-and-pin system. The brushed screw-in caseback has a sapphire crystal that makes it possible to observe the performance of the watch’s extraordinary movement.
The combination of the Co-Axial escapement and free sprung-balance lead to more stable performance over time and the addition of the silicon balance spring means that the movement delivers a level of reliability that allows OMEGA to offer each one with a four-year warranty.
The feature which has already generated the most enthusiastic response, though, is the chronograph sub-dial at 3 o’clock: the positioning of both the 60-minute and 12-hour recorders on the same counter allows the user to read the time intuitively.
