■ “Deep expression” created by circumferential gradation

The biggest highlight of the dial of the RN-AC0Q17Y is the circumferential gradation process that changes from light to dark from the center to the outer periphery. When viewed from the front, it has a depth that makes it look like the dial is emitting light from within, and its expression changes every moment depending on how the light hits it. The choice of copper itself is a unique color that combines the warmth of brown with a metallic feel, giving it a unique personality among diver watches that tend to be blue or black.

It has a sibling relationship with RN-AC0Q16N (gray), which is available in two limited colors at the same time. Both have the same gradation process, and one of their appeals is that you can choose from the contrasting impressions of stylish gray and warm copper.

■ “Clean arm” created by omitting the crown guard

A design feature of the Mako 40 series is that it does not have the crown guard that was found on conventional Mako watches. This gives the compact 39.9mm case a more streamlined look, creating a sleek appearance on the wrist that is different from larger diameter divers. It is designed to fit a wide range of users, making it easy to fit even on narrow wrists that don't suit a thicker case diameter.

The screw-type crown is firmly secured and ensures waterproof performance. Combined with the unidirectional rotating bezel, it maintains its functionality as a diver watch.

■ "Orient Mako's true value": F6722 x 20 ATM water resistant

The equipped caliber F6722 is an in-house movement that supports Orient's mechanical sports line, and is compatible with both automatic and manual winding. It has a 22-stone structure and keeps time in a mechanical range with an average daily difference of +25 to -15 seconds. It has a running time of over 40 hours, and it is convenient to be able to wind it by hand even when re-attaching it after taking it off for several days.

Water resistance is 20 ATM. Compatible with swimming and snorkeling, it is practical as a diver style watch. It gives you a great sense of security when you use water on a daily basis. It is also equipped with a sapphire crystal glass, making it a powerful specification that also ensures scratch resistance.

■ Buyer's comment

When I saw the actual copper color of RN-AC0Q17Y, I felt that it was warmer and deeper than I expected. The circumferential gradation process is really well done, and the expression of the dial changes depending on the angle of the light. This kind of design approach is rare in diver watches, and it is a watch that can go back and forth between sports and elegance with just the right amount of flavor. At this price, it comes with 20 ATM water resistance and sapphire glass, so it's easy to see why the Mako series has been supported for many years.
