2026 Omega Classic Moonphase. The Moonphase series of iconic watches continues Omega's longstanding tradition, beautifully combining a date display at 6 o'clock with the highly sought-after lunar and solar phases. Whether it's the timeless design of the dial or the cool, sculpted multi-faceted lines in stainless steel, it is all exceptional. It also features the Swiss ETA 2824-3 movement, with a date function and a large moonphase at 6 o'clock, a case diameter of 40mm, sapphire glass, Italian calfskin, and an original pin buckle.
