About this entry
73% of key specs known. Missing: lug-to-lug, hardening, AR coating, crown.
Open-heart automatic with Roman numerals at 12 and 6, a textured black bezel, an openwork 24-hour wheel at 9, the balance visible at about 7 and small seconds at about 4, matching the Miyota 82S7 layout; the dial reads "Sapphire" and "21 Jewels Automatic". The title's "Skeleton Tourbillon" is marketing: the photos show an open heart, not a tourbillon or a skeleton dial. Brand specs: "CITIZEN MIYOTA 82S7" (recorded), stainless steel case, 42mm, 12mm case thickness, 22mm band width, 5 bar, sapphire crystal, luminous hands, leather band 20.3cm with a "Push Button Hidden Clasp". The dimension drawing (42mm, 22mm, 203mm, 12mm, "Weight 71g", recorded as unspecified) and the description's parameter table (Miyota 82S7, sapphire glass, stainless steel case, genuine leather, 50M, 42mm, 22mm, 203mm, 12mm, 71g) agree. Display caseback from the photos; the bezel's material is not stated. AR coating and lug-to-lug are not stated. $129.99 for both colours on 2026-10-24, both sold out on 2026-10-25.
