Rare Early Military Artillery Observation Chronograph Timer Project

Rare Early Military Observation Chronograph Timer

An exceptionally rare early chronograph timer dating from the early twentieth century. Featuring a complex dual-crown chronograph mechanism, this specialised timing instrument was designed for precision interval measurement and timing applications.

Based on its unusual dual-crown configuration, sophisticated chronograph mechanism, and utilitarian design, it is believed that this instrument may have been intended for military observation, artillery observation, surveying, engineering, or other professional timing duties. However, its exact original application remains unconfirmed.

Instruments of this type are rarely encountered today, particularly in complete and restorable condition, making them highly desirable among collectors of early chronographs, military instruments, and technical timekeeping devices.

The watch is fitted with a sophisticated column-wheel chronograph movement, a high-quality design widely respected by collectors and enthusiasts of early precision timing instruments.

Condition

• Rare early military chronograph timer
• Dual-crown configuration
• Complex column-wheel chronograph movement
• Case diameter approximately 53.5 mm excluding crowns
• Original enamel dial
• Visible damage to the enamel dial
• Original hands present
• Hands may require adjustment or correction
• Overall condition remains good for its age

Mechanical Condition

Please note that this timer is offered strictly as a restoration project.

The movement responds to operation; however, the hands become stuck, the mechanism runs briefly and then stops.

A complete service, inspection, adjustment, and lubrication should be expected before reliable operation can be achieved.

Case Condition

The rear case section is damaged and will require repair.

Collector’s Note

Early military chronograph timers with dual-crown operation are rarely encountered on today’s market. Their specialised construction, historical significance, and complex movements make them highly desirable among collectors of military horology, scientific instruments, and early chronographs.

This is an increasingly scarce and highly collectible restoration project.
