The Omega Constellation Co-Axial 38mm Sedna gold watch is a unique and intriguing timepiece that connects a range of Omega historic factors. It combines new and old in a visually stylish way. Ask yourself, do you acquire the entire Constellation expertise with the opinion on a ring versus a full bracelet?Omega produced this Sedna gold ref. 188.8.131.52.02.001 Constellation watch as a small variation of 1,952 pieces in celebration of the year which Omega debuted the Constellation family in 1952. Within the opinion is an in-house made Caliber 8501 automatic Co-Axial motion. This resembles the 8500 motion, but the 8501 adds an 18k gold bridge over the balance wheel and an 18k rose gold automated rotor.In contrast to the less common limited edition Sedna gold Constellation is the steel Constellation Co-Axial Day-Date. This is quite much like the 8500 but includes a day of the week indicator with a window at 12 o’clock. This is Omega’s answer to Rolex’s day-date movement in the Rolex President models. The movement is pretty fine, and also to having a Co-Axial escapement and silicon balance spring, the 2 barrels provide 55 hours of power reserve. What’s more, the day and date indicator windows jump instantly at midnight.Almost the same watch as it is also available without the day of this week complication, if you aren’t considering that choice. I simply wanted to check it out as most people do not think of Omega as having a day/date dress watch. I didn’t actually know about the caliber 8602 until checking out this model. Be aware that this exact same movement is offered in some Aqua Terra watches as well.
