About this watch

The Omega Constellation Quartz 25.5 '95 Yellow Gold / Diamond / MOP, model number 1177.75.00, is a stunning luxury watch that combines elegance and precision. Crafted from luxurious yellow gold with Mother of Pearl (MOP) dial, this timepiece features gem-set indexes and bezel, adding to its unique iridescent quality. The Omega caliber 1456 movement provides precise accuracy, using a stepper motor delivering three impulses per minute.
