The Orient RA-AC0Q13E30B is a dynamic automatic sports watch in Orient’s Mako 40 collection, offering the practical strength of a diver-inspired timepiece in a compact, everyday-ready form. Built around a thoughtfully sized 39.9mm stainless steel case, it strikes a balance between sporty presence and effortless comfort. The model carries the adventurous DNA of Orient’s iconic diver line known informally as “Mako” among enthusiasts while presenting a sleeker, more versatile profile.
Distinctive Gradation Dial and Bold Aesthetics
This variation is distinguished by its gradation dial, where colour transitions subtly from lighter centre tones to richer outer hues, creating depth and visual texture at a glance. The carefully designed dial features luminous indices and hands that ensure excellent readability both above and below the water’s surface, maintaining a sporty yet refined character suited to active lifestyles.
Robust Mechanical Heart
At the heart of the RA-AC0Q13E30B beats Orient’s dependable in-house Calibre F6722 automatic movement with both automatic and manual winding, complemented by a hacking seconds function for precise time setting. It delivers a strong power reserve of over 40 hours, ensuring consistent performance throughout the week. This calibre is appreciated for its reliability and stability, reinforcing Orient’s reputation for producing high-value mechanical watches.
Durable Construction & Water Resistance
Equipped with a sapphire crystal, the watch offers excellent scratch resistance while providing crystal-clear views of the dial. The stainless steel unidirectional rotating bezel enhances its practical dive-style function, while the screw-down crown and case back help secure an impressive 200 metres (20bar) of water resistance, making it suitable for swimming, snorkeling and other water activities.
Sporty Styling Meets Everyday Functionality
A robust stainless steel bracelet with a fold-over clasp and safety release completes the build, combining durability with comfortable daily wear. The date display adds practical utility, while the overall aesthetic keeps the design clean and purposeful.
A Sporty Expression of Mechanical Confidence
The Orient RA-AC0Q13E30B embodies the best of Orient’s sports watch philosophy: dependable automatic mechanics paired with a versatile design that bridges active use and refined everyday wear. Its gradation dial and enduring construction make it a compelling choice for anyone seeking a mechanical diver-style watch with broad appeal and lasting performance.
