- Case and Dial Design
- The watch features a rectangular case constructed of nickel-chromium. The design integrates a functional sliding button situated on the case band, which is utilized for the operation of the chronograph mechanism. Measuring 23 x 44 mm, the case holds a mat silver dial. The dial layout includes painted index markers and features two primary complications. An auxiliary dial positioned at 6 o'clock serves as a 30-minute register, while the upper section at 12 o'clock hosts a 10-second chronograph dial graduated in fifths of a second, accompanied by an aperture displaying a 60-second register ring. The time is indicated by blued steel hands in the "Moderne" style.
- Production and Provenance
- The Invicta Chrono-Sport was produced during the 1930s, with a reported total manufacturing run of 50 examples. The current rarity of the model is highlighted by the auction report, which suggests that only about 6 original examples are currently known to exist. A similar example of this specific watch is cited in literature within the publication "Collezionare Orologi da Polso" authored by M. and O. Patrizzi, specifically located on page 163 of the text.
- Movement and Chronograph Mechanism
- The watch is driven by a 9-ligne tonneau-shaped movement that has been rhodium-plated. It contains 15 jewels and utilizes a lever escapement for timekeeping accuracy. The oscillation is governed by a monometallic balance paired with a self-compensating flat balance-spring. The chronograph function is characterized as a decimal single-button system capable of measuring to the fifth of a second. The auction description notes that in the 1980s, approximately 10 of these movements remained unused and were subsequently housed in 18-karat gold cases.
