Antique WWI German Navy U-Boat Submarine Officer Award Chronograph Wristwatch

Offered for your most serious consideration is a highly historic and monumental WWI-era German military chronograph wristwatch. During the First World War, the Kaiserliche Marine (Imperial German Navy) pioneered unrestricted submarine warfare, a theater of combat that required an entirely new class of precision instrumentation. In the cramped, high-pressure, and often dimly lit environment of an early U-boat, a commander’s ability to calculate speed, distance, and time was a matter of absolute life and death.

Originally manufactured as a massive navigational pocket instrument, this substantial 51mm timepiece was adapted with early fixed wire lugs, transitioning it into a wearable wrist chronograph. This was a critical tactical evolution, allowing an officer hands-free timekeeping while operating periscopes, issuing commands, or navigating charts. The prominent presence of dual Iron Cross motifs alongside the patriotic motto “Alles für Deutschland” (Everything for Germany) in traditional Fraktur script strongly indicates this was an exclusive presentation or award piece, bestowed upon an elite naval officer for distinguished service or operational success in the grueling Atlantic campaigns.

Detailed Condition & Specifications Report

The Award Dial & Hands The original pristine white enamel dial is a complex, highly functional masterpiece of military instrumentation, preserved in truly exceptional condition.

• Military Motifs: The center of the dial proudly displays two highly detailed German Iron Crosses flanking the bold patriotic inscription, immediately signifying its prestigious military heritage.

• Concentric Chronograph Scales: The outer edge features a highly intricate, multi-colored tachymeter and telemeter track, meticulously calibrated in red, green, and black (Kilomètres à L’Heure Base 1000). These scales were critical tactical tools: a commander could use the chronograph to measure the time between seeing an enemy ship’s cannon flash and hearing the report to calculate distance, or time a vessel over a known distance to calculate its speed for a torpedo firing solution.

• Timekeeping & Registers: The hours are designated by bold black Arabic numerals for high legibility. A 30-minute chronograph totalizer is positioned at the 12 o’clock position, perfectly balanced by a running subsidiary seconds dial at 6 o’clock.

• Hands: The time is tracked by dark, stylized steel hands, complemented by a needle-fine central chronograph sweep-seconds hand that allows for fraction-of-a-second precision.

The Case & Strap

• Case Exterior: The substantial 51mm military case is crafted from a durable white metal alloy (likely nickel-silver or steel) with a smooth, polished finish designed for utilitarian durability.

• Fixed Wire Lugs: The case is fitted with heavy, articulated wire lugs, typical of the earliest “trench watch” adaptations that moved timepieces from the pocket to the wrist.

• Inner Case Back: The interior of the secure snap-on case back is cleanly stamped with the serial number “118376”.

• The Strap: The watch is securely mounted on a robust, high-quality black leather strap with stitched detailing and a classic steel buckle, ensuring it is ready for immediate display or very careful wear.

The Precision Movement

• Mechanics: Powering this historical instrument is a pristine, high-grade mechanical chronograph movement. It features a highly desirable traditional column-wheel chronograph mechanism, an architectural design celebrated by collectors for its long-term durability and the incredibly precise, tactile feel of the pushers.

• Finishing: The movement is beautifully finished with frosted gilt brass plates, which provide a striking visual contrast against the polished steel chronograph levers, gears, and blued screws.

• Operating Condition: Despite its age and intense combat provenance, this exceptional military award chronograph remains in perfect working order. The manual-wind movement runs strongly and keeps accurate time, while all chronograph functions start, stop, and reset precisely to zero.

This antique military presentation timepiece is a functioning piece of world naval history and is sold exactly as photographed. Please review all high-resolution images carefully, as they form a definitive part of the description.
