The Reservoir Battlefield D-Day is rugged military watch with the brand’s signature trio of complications — retrograde minute, jumping hour, and power reserve — along with an important message: It commemorates the 1944 D-Day battle on Omaha Beach, the code-named Operation Overlord.

The 43mm case is 316L stainless steel with a brushed gunmetal PVD finish, which seems like the perfect material and finish for a watch that celebrates the WWII all-terrain vehicle, a symbol of tenacity, durability, and ingenuity.

The purity of the functions indicates they are designed for accuracy and readability, whether syncing for the battlefield or the sports field. The retrograde minutes dominates the dial, spreading clockwise from the 8 o’clock to the 4 o’clock position in a stencil-style army font that you can’t miss. The space at the 6 o’clock position is allotted to the jumping hours, in a window hovering just above the power reserve, which is given the E/F (Empty, Full) designation, in tribute to army vehicles. The retrograde minute at 240° recalls the rev counters, the manometers, and the altimeters.


The jumping hour in the aperture recalls the kilometer counters, and the power reserve display echoes the fuel and oil gauges. Above the hour window is the national emblem of the U.S. Army, the white star. All markings are white against a military sand-khaki background, made extra-readable by an anti-reflective sapphire crystal. The strap is khaki-colored leather, but being a military watch, it naturally comes with an extra NATO strap.

The movement is a modified automatic ETA caliber 2824-2 with a patented Reservoir-made module of 134 components for the retrograde minutes and jumping hours functions. Although Reservoir is based in Paris, the timepieces are Swiss-made. For the module, Reservoir joined forces with Télôs Watch, a well-known Swiss maker of complications. The ETA caliber 2824-2 is one of the most well-known movements in the watch industry, acclaimed for its reliability and precision, oscillating at 28,800 vph. It has a 37-hour power reserve. The movement is assembled and meticulously calibrated in La Chaux-de-Fonds, Switzerland, with attention to every minor detail.

Operation Overlord took place on June 6th, 1944 when U.S. Army soldiers descended upon Omaha Beach and the Liberty ships dropped off the historic all-terrain vehicles driven by committed soldiers, full of adrenaline and focused on freedom. The Battlefield evokes this “land force,” this mechanical engineering vital for winning the war.


Reservoir was founded by François Moreau, who has long been fascinated by vintage measuring instruments. His watches are a tribute to racing drivers, pioneers of the aerospace conquest, and to all the heroes determined to push the limits of their time. After 25 years of management experience in the banking industry, Moreau decided to launch Reservoir in 2015. He was driven by an acute sense of design and creativity, along with a desire to offer a genuine and affordable alternative to luxury watchmaking.

The Reservoir Battlefield D-Day is water-resistant to 50 meters and has an international warranty of three years. It is priced at $3,980 USD.
