Reservoir’s Mark II Series Gives the Instrument Watch a Sharper Edge

Reservoir has built its identity around watches that look and feel like mechanical instruments rather than conventional wristwear.

The Mark II Series keeps that dashboard spirit intact, but gives it a more assertive exterior with a faceted steel case, an integrated bracelet and three dial executions drawn from automotive and aviation cues.

It’s a meaningful update for a brand whose appeal has always lived in the tension between nostalgia, function and a touch of mechanical theatre.

At a glance

A sharper case for Reservoir’s instrument language

The biggest shift in the Mark II Series sits around the dial rather than on it.

Reservoir has moved away from the softer case profile of earlier models and adopted a more architectural 316L stainless steel construction measuring 41mm across.

The case uses polished facets against vertically brushed surfaces, creating the sort of industrial contrast that suits the brand’s cockpit-and-gauge vocabulary.

Visible screws at the front reinforce that mechanical-instrument character without making the watch feel like a costume piece.

The integrated bracelet is just as important to the redesign, giving the watch a sportier stance and a more complete visual identity on the wrist.

Its brushed and polished links continue the finishing language of the case, while the screw-down crown and 50 metres of water resistance keep the package practical for everyday wear.

Three dials with distinct mechanical moods

All three versions share Reservoir’s familiar display architecture, with the retrograde minutes spanning the upper half of the dial and the jumping hour aperture positioned at 6 o’clock.

A power-reserve indicator sits below the hour window, giving the layout a pleasingly balanced vertical axis.

The GT Tour Mark II is the most overtly automotive of the trio, using a matte black dial with red-orange accents across the minute track and retrograde hand.

It has the punch and legibility of a performance gauge, with just enough colour to make the display feel alive.

The Kanister Mark II takes a more vintage route, pairing pastel green details with mid-century-style typography and a textured black centre.

Its concentric minute section and white jumping hand give it a softer period character, closer to an old speedometer than a modern rev counter.

The Airfight Jet Mark II leans into aviation, using high-contrast yellow and white markings against a black ground.

It’s the most utilitarian of the three, and arguably the one that most directly expresses Reservoir’s fascination with cockpit instrumentation.

The RSV-240 movement keeps the show moving

Behind the display is Reservoir’s calibre RSV-240, visible through a sapphire exhibition caseback.

The movement combines a heavily modified La Joux-Perret G100 base calibre with a proprietary 113-component complication module developed with Telos.

That module manages the jumping-hour and retrograde-minute indications, both of which demand more energy than a conventional three-hand display.

Even with those demands, the movement delivers a stated 56-hour power reserve, a strong figure for a watch with this kind of animated time display.

The appeal here isn’t just the technical architecture, but the way it turns timekeeping into a small performance.

The minute hand travels its arc before snapping back, while the hour jumps cleanly in its window, giving the wearer a display that feels more kinetic than decorative.

Details & Specifications

The Mark II Series feels like a smart evolution rather than a reset.

Reservoir has strengthened the case, sharpened the wrist presence and preserved the playful instrument-display format that gives its watches their personality.

For collectors drawn to mechanical displays with character, this is Reservoir speaking its own language more fluently than before.
