About this entry
60% of key specs known. Missing: lug width, weight, hardening, crown, lume, bracelet offered.
Three-hand pilot's watch with an "MKIV" logo at 6. Brand specs: case Ø38mm, 11mm high including the crystal, 46mm lug-to-lug, 5 atm, sapphire with double AR coating; movement 11½ lignes (Ø25.60mm), 4.60mm high, 28,800 vph, 38h, 26 jewels (Incabloc), lift angle 50°. The pages don't name the caliber; those figures match Sellita's SW200-1 sheet (the ETA 2824-2 has 25 jewels) and the brand's other three-hand models use the SW200-1, so it is recorded as an SW200-1. The spec block also carries a stray "22", not recorded as a lug width. The MK IV pages say the case is cast from a Panavia Tornado turbine (the rest of the site says F-104 Starfighter). No date window in the photos (complications set without date). Gallery photos show the Nero and Bianco on a three-link steel bracelet as well as leather straps, but each listing has one price and no bracelet option. The Verde page has no spec text. The brand's terms of sale say prices include IVA (Italian VAT).
