Dive Watch Review – Reservoir Hydrosphere Greg Lecoeur Limited Edition

Let’s be trustworthy, all of us spend an excessive amount of time taking a look at watches. Day in, day trip, it’s a continuing onslaught of little spherical gadgets with three palms that inform us the place we at the moment are in our rotation round Earth’s axis. It will possibly get somewhat monotonous, and a little bit of burnout is inevitable. However, each every now and then, a model comes together with one thing new and recent to shake you out of the haze and take discover. One thing completely different sufficient to be attention-grabbing, however not so out-there that it turns into absurd. Reservoir is a type of manufacturers, and we’re going to take their Hydrosphere dive watch to sea and put it via the rigours of the depths.


Launched in France in 2015 by ex-banker François Moreau to supply a artistic and accessible different to luxurious watchmaking, all Reservoir watches take inspiration from instrument dials and gauges of the previous, from race automobiles to airplanes, and all have one factor in frequent: the retrograde minute and leaping hour problems. For anybody unfamiliar with a retrograde complication, it merely signifies that the minute hand jumps again to zero after finishing its minute depend, reasonably than persevering with round in a perpetual circle. This permits the 60-minute hand to take up much less dial actual property and be expressed in additional artistic configurations than a steady circle. 

In Reservoir’s design, the minute hand counts up clockwise round a 240° radial till it will get to the 60-minute mark, the place it magically and instantaneously jumps again to zero, and begins the method throughout. On the identical time the hour marker, an Arabic numeral on a disc, proven via a barely magnified cyclops aperture on the 6 o’clock place, immediately jumps ahead to the subsequent hour. It’s a reasonably distinctive and attention-grabbing option to inform the time, and positively unusual within the watch world.

The watch we’re diving with at the moment is the Reservoir Hydrosphere, the model’s dive watch providing. And never simply any Hydrosphere, that is the bronze Greg Lecoeur version, a collaboration with the award-winning underwater photographer. In case you are unfamiliar along with his wonderful work, you possibly can test it out right here. Greg and Reservoir have teamed as much as convey out a restricted version of the bronze Reservoir Hydrosphere, with a vibrant blue dial that evokes the colors of the ocean. As a really cool bonus, purchasers of this restricted version of fifty watches had been supplied a half-day dive with Greg Lecoeur within the Port-Cros nationwide park in France again in September. It’s good to see manufacturers and their ambassadors personally interacting with their prospects in methods like this, and hopefully, different manufacturers will take discover. That day certainly created a lifelong reminiscence tied to the watch, and isn’t that what watches like this are all about? Kudos to Reservoir and Greg Lecoeur for making that occur.

The Reservoir Hydrosphere On land

Like different watches within the Hydrosphere assortment, this can be a 45mm diameter, 15mm thick device watch, meant for use and abused. Inside motive, in fact. It’s completely spherical in form, conserving with the instrument theme, and made fully of bronze (minus the caseback in stainless-steel, as nobody needs a patinated wrist). The dial has a beautiful sunburst blue design, with a small Greg Lecoeur signature at 3 o’clock, a pleasant and delicate option to point out the collaboration with out throwing it in our faces. The dial additionally options absolutely lumed numerals each 10 minutes and indices each minute. The minute monitor is adorned with pink, inexperienced and blue areas in 20-minute intervals, very like a gasoline gauge may be to point various ranges of fullness.

The wristwatch model of a gasoline gauge, the ability reserve indicator, is a skinny curved bar down on the 6 o’clock place with a white dot that strikes alongside the identical blue/inexperienced/pink monitor to point roughly how a lot of the 37-hour energy reserve you may have remaining. There’s additionally a small spinning disc across the centre of the dial that capabilities as a operating indicator. Understanding that your watch is operating turns into fairly necessary when timing issues underwater.

Talking of the ability reserve brings us beneath decks to the motion. The retrograde minute and leaping hour problems are made doable by a proprietary and patented 124-component module, created by Reservoir and assembled in Switzerland; it’s utilized in all of their watches. This module is powered by the ETA 2824-2 automated motion, which is about as tried-and-true a motion as you may get lately. 

On the wrist the Hydrosphere wears a lot smaller than its 45mm measurement would have you ever consider. It isn’t small by any measure, however most likely wears somewhat extra like a 42mm watch, thanks in no small half to the whole lack of lugs. The great royal blue nato strap is held in place by a small buckle that’s connected to the case with two screws. You possibly can take away the screws and the buckles to instantly screw within the included black rubber strap, however given the built-in nature of the strap system, you may be restricted to the rubber or any 22mm nato strap. Fortunately there are tons of of various types of these on the market.

The Reservoir Hydrosphere At Sea

Earlier than we take the Hydrosphere within the water, let’s speak about its timing bezel. You may be pondering, “Hey, there’s no approach that bezel can time appropriately, what with the retrograde complication and all!” And also you, sir or madame, can be right. To deal with your most astute commentary, Reservoir has applied a intelligent little bezel trick. There are two separate timing tracks, colored pink and blue. In case your dive is starting earlier than 45 minutes have elapsed within the hour of the day, you merely learn the pink monitor, but when your dive is starting after 45 minutes have elapsed you turn over to studying from the blue facet after the retrograde bounce. If it sounds somewhat convoluted, it certainly is, and it’s actually my solely actual criticism concerning the watch. 

The bezel solely has pips for timing as much as half-hour, which is successfully ineffective in a contemporary diving state of affairs, the place dives routinely go 45 minutes or longer. There’s additionally solely a numeral for “15” on both scale, pink or blue. Because of this you must depend ahead or backwards from 15 to determine the place you’re within the timing, and when you must bounce forwards and backwards from pink to blue scale and earlier than and after the retrograde bounce it may be somewhat complicated. If my fast Photoshop mockup is right, there can be a option to make the bezel time as much as a full hour, irrespective of the place you begin, by using a twin scale and repurposing the bezel actual property that’s at the moment being taken up with the phrase “Hydrosphere”.

I perceive the design issues, and the bezel seems to be very cool, however in a dive watch, I’ll all the time select somewhat extra litter if it provides performance. Because it stands, the one option to really time a dive with the Hydrosphere can be to start out your dive proper on the hour, or simply set the watch again to the hour, dropping the flexibility to inform time. Neither are very ultimate choices. You possibly can definitely use the Hydrosphere to time decompression stops, or some other shorter underwater intervals, however as a full dive timer, it falls somewhat bit quick.

Bezel woes apart, that is one severe chunk of package. I wore it on the nato strap and it was completely snug and safe within the water. Each the nato and the rubber strap match properly on my small 16cm wrist, but additionally have sufficient further that they’d simply match over a wetsuit. The scuba diving atmosphere is the place the Reservoir design language actually sings. Between the boats that take us out into the deep blue yonder, and all of the gear we don earlier than submerging, scuba diving is foolish with gauges and meters, and the Hydrosphere matches proper in. Undoubtedly don’t set it down within the engine room of an older boat or you’ll by no means discover it once more.

Underwater the watch seems to be incredible, conjuring the sensation of a steampunk “20,000 Leagues Below the Sea”, or “The Undersea Adventures of Captain Nemo” if anybody remembers that previous cartoon. If we’re being trustworthy, I believe that’s the underwater world that every one divers, secretly or not-so-secretly, need to dwell in. The diving world of yore, a world of minimal gear and most exploration and surprise. I daresay the Hydrosphere is the one fashionable dive watch that belongs in that world, and that may be a excessive praise. The bronze is an ideal match with the old-timey maritime motif, trying like an identical set with a steam gauge or sextant or a marine chronometer, and the blue of the dial melds proper into the color of the ocean.

With just a few small tweaks to the bezel, the Hydrosphere can be on a really shortlist for my single, everlasting diving watch. It will by no means exchange a pc for Twenty first-century diving, nevertheless it has the precise proper parts of caprice, nostalgia and fashionable toolishness, within the actual proper portions to make it an absolute pleasure of an underwater companion.
