Orient Mako 40 RA-AC0Q16N30B Automatic Diver‑Style Watch — Spring/Summer 2026 Collection
The Orient Mako 40 RA-AC0Q16N30B is a compact automatic diver‑style watch within the Diver Design 40 collection, combining classic sport character with refined mechanical performance. Built around a versatile 40mm case and vibrant dial colour, it balances everyday practicality with the adventurous spirit of a diver‑inspired timepiece.
With a polished and brushed stainless steel case measuring approximately 39.9mm in diameter, the RA‑AC0Q16N30B showcases a grey sunburst dial that subtly shifts tone under varying light. Its sapphire crystal delivers excellent scratch resistance, and the unidirectional rotating bezel enhances its sporty aesthetic and functional timing capability. Luminous hands and indices ensure clear readability in all conditions, while the discreet date window at 3 o’clock adds everyday utility.
