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

Orient Mako vs Kamasu vs Ray at a glance

The Orient divers in this comparison have more in common than not. Every one is rated to 200 m, runs an Orient automatic caliber and comes in a stainless steel case. The real choices come down to case size, caliber, crystal and strap.

Orient was founded in Japan in 1950 and is now part of Seiko Epson. The dive watch lineup covered here splits into three size groups: 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.

Prices in this guide come from Amazon US in October 2026. They change, so check the product cards for the current price.

Two calibers matter. 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 through the crown and stop the seconds hand to set the time. The F6922 has 22 jewels, beats at 21,600 vph and offers about 40 hours of power reserve.

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) measures 39.9 mm across and 12.8 mm thick, with a 46.5 mm lug-to-lug. That's noticeably smaller than the 41.5 mm-plus models here. The listing also includes a flat sapphire crystal, a screw-down crown, a screw-in case back, 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 caliber and sapphire crystal but has a brown dial. It's 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) puts a white dial on a steel bracelet with synthetic sapphire, but it costs more, 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 gray sunburst dial. The listing mentions a screw-down crown, a 120-click unidirectional bezel, lume and a day-date display driven by the F6922. We couldn't confirm the crystal type, so check our Orient Mako 3 review for details. It runs 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's listed with synthetic sapphire, a screw-down crown, the 120-click bezel and a green dial. That combination costs more, around $300 to $350. Our Orient Kamasu review goes into more depth.

Mako II and Ray II, the classic sibling design

The Mako and Ray are sibling designs. On paper, the Mako II (FAA02001B) and Ray II (TAA02005D9) share a 41.5 mm case, 13 mm thickness, a 22 mm lug width, the F6922 caliber, 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. Only two things differ: the Mako II has a black dial and runs about $200 to $250, while the Ray II has a blue dial and costs about $250 to $300. Choose by dial color and budget.

Kano Big Mako, the largest option

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

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, a screw-down crown, a screw-in case back, lume and a blue two-piece rubber strap. It's in the lowest price range here, around $200 to $250, and suits buyers with larger wrists who want more dial presence.

Which Orient diver to buy

For smaller wrists, get the Mako 40 Blue, or the brown or green versions if you prefer a different color or strap. Either way, you get sapphire and a 39 to 39.9 mm case for $250 to $300.

For a day-date with sapphire, the Kamasu is the one to get. It costs more, but it's the only watch here confirmed with both the F6922 and sapphire.

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