Vintage Gizbo Silo Stainless Steel Wristwatch Caseback

This is the caseback and rear housing of a vintage Gizbo Silo wristwatch, likely dating from the 1980s or 1990s. The casing is constructed from base metal with a brushed finish, while the circular snap-off caseback is explicitly marked as 'STAINLESS STEEL BACK'. The overall shape of the watch head is angular and geometric, suggestive of retro-digital or novelty designs from that era. Key inscriptions on the caseback include the brand name 'GIZBO SILO' along with a 'U.K. REG. NO. 2026777' and a separate serial or production number '00028084'. The item shows significant signs of wear and age, including heavy scratching across the stainless steel surface and visible debris or oxidation buildup around the seam where the back meets the main body. The integrated metal link bracelet is visible at the top, secured by a standard spring bar. The crown is located on the left side of the casing, which is atypical and may indicate a specific design for left-handed wear or a unique movement configuration. The level of craftsmanship indicates a mass-market, utilitarian grade rather than luxury horology.
