About this entry
67% of key specs known. Missing: lug-to-lug, thickness, hardening, AR coating, crown.
Skeleton automatic in a case made entirely of sapphire crystal (steel crown), 40mm, 79 g, 3 ATM, 20mm leather strap, each version limited to 10 pieces with the owner's name and edition number engraved on the rotor. Both versions are sold out: the original (2,500 EUR) sits in the store's "descatalogados" (discontinued) category, and the blue version is listed as "AGOTADO – Antarctica Azul" (2,750 EUR, sold with a watch winder as a gift). The case material is recorded as "other" because the schema has no sapphire case material. Movement: the blue version's spec list names the STP6-15 skeleton (28,800 vph, 26 jewels, 44h); the original's says "movimiento suizo automático skeleton STP1-11". Grail Watch lists the STP6-15 as the skeletonised member of the STP1-11 family (no date), and the original's photos show the same skeleton layout with no date window, so both are recorded as STP6-15 and the original's "STP1-11" is taken as the family name; the movement finish differs (silver-tone on the original, blue on the Azul). Variant names are ours, from the photos. Water resistance: "Sumergible 3 ATM" / "Resistente al agua 3 ATM"; the original's caseback reads "30 meters".
