Which Orient Diver Should You Buy? Mako vs Kamasu vs Ray

Orient Mako vs Kamasu vs Ray at a glance

The Orient divers in this comparison have more in common than not. Every listing here is water resistant to 200 m, uses an Orient automatic calibre and has a stainless steel case. The real choices come down to case size, calibre, crystal and strap.

Orient was founded in Japan in 1950 and is now part of Seiko Epson. Its dive watch line-up falls into three size groups here: the Mako 40 family at 39 to 39.9 mm; the Mako 3, Kamasu, Mako II and Ray II at 41.5 to 41.8 mm; and the Kano Big Mako at 44 mm.

The price bands in this guide are taken from Amazon US in October 2026. Prices change, so check the product cards for the current figure.

There are two calibres to know about. The F6722 shows the date only, while the F6922 shows the day and date. Both are in-house automatics that hand-wind and hack, so you can wind them via the crown and stop the seconds hand to set the time. The F6922 has 22 jewels, beats at 21,600 vph and offers a power reserve of about 40 hours.

A 200 m rating covers swimming and snorkelling. Bear in mind, though, that some listings qualify it, describing the watch as suitable for surface water sports or skin-diving rather than scuba diving.

The Mako 40 family, the smaller sapphire option

Orient Mako 40 RA-AC0Q14L, 40mm, Blue Dial, Silver Stainless Steel Bracelet

View product

The Orient Mako 40 (RA-AC0Q14L) has a 39.9 mm case that is 12.8 mm thick, with a lug-to-lug span of 46.5 mm. That makes it smaller than the larger models here, which start at 41.5 mm. It has a flat sapphire crystal, a screw-down crown and a screw-down caseback. On top of that you get a unidirectional rotating bezel, luminous hands and indices, and a steel bracelet with a trifold deployant clasp.

The Mako 40 Brown (RA-AC0Q15Y) uses the same F6722 calibre and sapphire crystal but has a brown dial. It is listed at 39 mm across and 12 mm thick. Both cost around $250 to $300.

If you prefer rubber, the Mako Green (RA-AC0Q11E) pairs a 39 mm case and sapphire crystal with a rubber strap and a standard 20 mm lug width. The Mako White (RA-AC0Q03S30B) brings a white dial on a steel bracelet with synthetic sapphire, but it costs more, at around $300 to $350.

Mako 3 and Kamasu, the 41.8 mm day-date pair

The Orient Mako 3 (RA-AA0819N39B) steps up to a 41.8 mm case, 12.8 mm thick, with a 22 mm lug width and a grey sunburst dial. The listing mentions a screw-down crown, a 120-click unidirectional bezel, lume and a day-date display from the F6922. Its crystal type is not confirmed, so have a look at our Orient Mako 3 review for details. It costs around $250 to $300.

Orient Kamasu RA-AA0004E39B, 42mm, Green Dial, Silver Stainless Steel Bracelet

View product

The Orient Kamasu (RA-AA0004E39B) has the same 41.8 mm diameter and 12.8 mm thickness, with a 46.8 mm lug-to-lug and 22 mm lugs. It is listed with synthetic sapphire, a screw-down crown, the 120-click bezel and a green dial. That combination pushes the price up to around $300 to $350. Our Orient Kamasu review goes into more depth.

Mako II and Ray II, the classic sister models

The Mako and Ray are sister models. The Mako II (FAA02001B) and Ray II (TAA02005D9) share a 41.5 mm case, 13 mm thickness, 22 mm lug width, the F6922 calibre, a 120-click unidirectional bezel and a steel bracelet.

Orient Ray II TAA02005D9, 42mm, Blue Dial, Silver Stainless Steel Bracelet

View product

Both use a mineral crystal, which scratches more easily than sapphire. The only differences are dial colour and price: the Mako II is black and costs around $200 to $250, while the Ray II is blue and costs around $250 to $300. Choose by colour and budget.

Kano Big Mako, the largest option

Orient Sports RA-AA0916L, 44mm, Blue Dial, Blue Rubber Strap

View product

The Kano Big Mako (RA-AA0916L) is the outlier at 44 mm, 12.9 mm thick, with 22 mm lugs. It runs the date-only F6722 and is listed with a mineral crystal, screw-down crown, screw-down caseback, lume and a blue two-piece rubber strap. It is among the cheapest here, at around $200 to $250, and suits wearers with larger wrists who want more dial presence.

Which Orient diver to buy

For smaller wrists, the pick is the Mako 40 Blue, with the brown or green versions as alternatives if you prefer a different colour or strap. You get sapphire and a 39 to 39.9 mm case for around $250 to $300.

For a day-date with sapphire, the Kamasu is the one to buy. It costs more, but it is the only listing here that confirms both the F6922 and a sapphire crystal.

If you like the classic Mako II or Ray II look, take the Mako II if price matters most and the Ray II if you want blue. And if you want the biggest case, the Kano Big Mako is the only 44 mm option.
