Author POV

Drop the 'M' from the name and Omega also drops the metal case: this is ceramic, at 43.5mm the largest case I've measured in this family, and it wears that size differently than the metal 300Ms because ceramic is both harder-wearing against scratches and lighter than steel at equivalent volume. Caliber 8806 is the same movement running through several steel references here, so nothing about the mechanics separates this piece — only the case material and the extra 1.5mm do. Rubber strap, no date, black dial; ceramic case builds consistently score higher for scratch-resistance and lower for repairability on my sheet, a trade every ceramic buyer should understand going in.
