About this entry

60% of key specs known. Missing: lug-to-lug, hardening, AR coating, crown, lume, bracelet offered.

Slim automatic with an open-heart aperture at about 7 o'clock, Roman numeral 12, stud markers and "Automatic" and "Sapphire" printed on the dial. Brand specs: automatic (the spec list doesn't name the caliber; the description's product-information images say "Movement: MIYOTA 90S5" and "MIYOTA 90S5 Automatic Self-Wind", recorded), stainless steel case, 40mm, 8mm case thickness, 20mm band width, sapphire crystal, leather band 20cm with a "Push Button Hidden Clasp". Water resistance: the spec list says 3 bar, but the description's details table and "50M waterproof" panel and the C8140ML set's spec list and parameter table say 50 m, which is recorded. The dimension drawing (40mm, 8mm, 20mm, 200mm, "Weight 73g", recorded as unspecified) and the details table (40mm, 20mm, 200mm, 8mm, 73g) agree. Display caseback and butterfly deployant clasp from the set's photos and the description images. Case tones per colour from the photos (the white dial has a steel case with a rose gold-tone bezel, the blue dial an all rose gold-tone case); the plating is not described. Lume, AR coating and lug-to-lug are not stated. $169.99 for both colours on 2026-10-24, both sold out on 2026-10-25. The store also lists a C8140ML "couple's set" pairing this watch with the 34mm C8140L ladies' watch, in four combinations ("White Blue" with a white men's and a blue ladies' dial, "Blue White" the reverse, "Rose Gold White" both white, "Rose Gold Blue" both blue), $289.99 on 2026-10-24 and sold out on 2026-10-25. Its title and parameter table name the Miyota 90S5 and give the men's watch as 40mm, 8mm, 20mm strap, 200mm, 73g and the ladies' as 34mm, 8mm, 16mm, 190mm, 55g; its spec list's "40.34mm", "20.16mm" and "20.19cm" are not used. The set price is below the $339.99 the two watches cost separately, which suggests it covers both; the listing doesn't say. No independent review was consulted.
