Design
- Visible features
- • Three-tier teak box construction with finger-jointed corners. • Linear power reserve scale located at the bottom half of the dial. • Visible balance lock lever positioned near the 8 o'clock marker. • Brushed steel bowl with a distinctive circular, gear-toothed bezel profile.
- Dial and Timekeeping
- The dial is a black, two-layer construction. It utilizes luminous sunk baton indexes for most hour markers, with Arabic numerals used for the quarters. Time is read via black luminous baton hands. An outer track records the minutes. Functionality includes a subsidiary seconds dial and a linear power reserve indicator located above the 6 o'clock position, capable of displaying up to 52 hours of duration. A balance lock mechanism is integrated into the dial layout at the 8 o'clock position to immobilize the balance during transport.
- Housing and Exterior
- The marine chronometer is contained in a three-tier teak wood box. This wooden structure serves as the primary external housing, featuring a glazed top section that permits viewing of the instrument while the box is closed. The lid is hinged, and the case is fitted with steel handles for transport. Mounted within this box is the brushed steel bowl. This bowl supports the main chronometer assembly and incorporates a screwed-down bezel. The instrument is gimbaled, allowing it to maintain its position relative to the horizon regardless of the motion of a vessel.
- Movement and Technical Specifications
- The Caliber OP XX movement is constructed primarily from brushed steel and is composed of 15 jewels. It employs a traditional fusee and chain mechanism designed for constant force delivery to the escapement. The escapement itself is a spring-detent type, housed within two circular plates. The timing assembly features a cut monometallic compensation balance equipped with cylindrical weights. It also utilizes a free-sprung helical balance spring with terminal curves, a design intended for high-precision chronometric performance.
