Based mostly upon the utilitarian case design of a chronograph that was produced for the German Air Power in 1984, the Tutima M2 assortment is the model’s lineup of sturdy performance-oriented sports activities watches. Through the years, the M2 lineup has expanded to incorporate a reasonably various assortment of various fashions, and whereas some lean right into a extremely utilitarian and purpose-built design ethos, others take the core blueprint of the M2 sequence and switch it into one thing that may extra simply exist in on a regular basis life. Arguably a number of the greatest examples of the latter number of fashions are the 40mm variations of the Tutima M2 Seven Seas S that had been launched on the very finish of 2022, which take the underlying design of the model’s ultra-robust diver and render it in a extra compact and refined general package deal.
Throughout the higher Tutima M2 assortment, the Seven Seas vary is the model’s lineup of dive watches that rework the M2’s modernized tonneau-shaped case right into a function-forward diver with a 500-meter depth score. Whereas the unique Seven Seas is crafted from titanium and presents a extremely sporty and utilitarian design, the Seven Seas S is made out of stainless-steel, and it embraces a usually extra refined general aesthetic. Whereas the unique Tutima M2 Seven Seas S was launched with a 44mm case, a smaller 40mm model was later added to the gathering, and its lowered dimension and revised proportions make it a superb candidate for on a regular basis put on and use, whereas nonetheless providing the identical borderline-excessive water resistance that may fairly actually accompany you to the underside of the ocean.
Crafted from brushed and polished stainless-steel, the case of the smaller model of Tutima M2 Seven Seas S presents an similar form and profile to its bigger siblings, though it has been lowered in nearly each dimension attainable. Measuring 40mm in diameter by 12.5mm thick, even the on-paper specs provide the impression that this specific model of the Seven Seas S shall be fairly manageable; nonetheless, Tutima M2 watches are inclined to put on even smaller than their official dimensions. Since Tutima’s M2 case doesn’t have any lugs within the conventional sense of the phrase, the “lug-to-lug” measurement for the 40mm Seven Seas S is available in at simply 40.5mm, and even while you consider the best way that the end-links stick out previous the perimeters of the case, you might be nonetheless solely an approximate general distance of 49mm. Moreover, regardless of being half a millimeter thinner than its full-size sibling, the smaller 40mm model of the Tutima M2 Seven Seas S remains to be capable of provide the very same 500-meter depth score.
Identical to the bigger Tutima M2 Seven Seas S fashions, a signed screw-down winding crown sits between two giant guards on the 3 o’clock location, whereas the strong screw-down stainless-steel caseback options a big engraving of a ship. On the other facet of the case, a 2.5mm thick flat sapphire crystal with anti-reflective therapy protects the dial, and simply as you’d anticipate from a dive watch, the crystal is surrounded by a unidirectional rotating timing bezel. The outer bezel ring includes a combination of scalloped edges with grooved sections, and fitted to this specific model (reference 6156-06) is a inexperienced ceramic insert with a 60-minute elapsed time scale in white. Whereas the sting of the bezel isn’t absolutely the best to grip, it does provide a easy and strong 60-click motion with nearly zero perceptible backplay by any means.
The dials fitted to the Tutima M2 Seven Seas S fashions all have a barely extra refined and dressy look in comparison with these from the usual titanium Seven Seas vary, and an enormous a part of this is because of their hour markers, that are utilized tapered batons with polished sides and a rhodium-plated end. On the model featured right here (ref. 6156-06), the dial is a wealthy inexperienced shade with a radial dégradé impact that darkens to black in the direction of the periphery. Identical to the dials fitted to the bigger model of the M2 Seven Seas S, the 40mm mannequin additionally includes a date window on the 6 o’clock location, and the inexperienced dial variant options all of its textual content in crisp white printing for added distinction. Whereas the hour and minute palms obtain a elegant end to go with the indexes, the seconds hand is vivid crimson for an extra sprint of shade, and all three of the palms, plus every one of many hour markers and the pip on the bezel are completed with Tremendous-LumiNova that emits a inexperienced glow to assist with visibility in low gentle settings.
Powering the 40mm Tutima M2 Seven Seas S is identical Tutima Caliber 330 computerized motion that may be discovered inside its bigger siblings. At its core, the Tutima Cal. 330 is basically the model’s model of the favored ETA 2824 or SW200, and as such, it presents a confirmed design and the acquainted specs of working at a frequency of 28,800vph (4 Hz) with an influence reserve of roughly 38 hours. Though the Tutima Cal. 330 is undeniably a bit inauspicious, it’s also a really acceptable choice for strong divers like these from the M2 vary, and whereas it’s straightforward to put in writing this motion off for its ubiquitous design and relatively brief energy reserve, it’s finally a really sensible choice on the subject of every day use and long-term possession. That mentioned, as a consequence of the truth that variations of this identical core motion will be present in watches at considerably lower cost factors, it will have been good to see Tutima use a chronometer-certified equal, though this may have inevitably resulted in the next retail worth level, with solely marginal real-world advantages.
Identical to the bigger model of the M2 Seven Seas S dive watch, Tutima presents the 40mm mannequin with the choice of both a stainless-steel bracelet or a leather-based and rubber strap that’s color-matched to the dial of the precise reference. That includes a rounded H-Hyperlink design, the bracelet seems to have an built-in construction; nonetheless, the brief finish hyperlinks really mount into a reasonably customary 23mm hole on the decrease facet of the case. With that in thoughts, because the finish hyperlinks connect to the case with pins fairly than spring bars, the bracelet isn’t one thing that may be shortly swapped out (not to mention eliminated with out the usage of any instruments). Moreover, because the distance between the connecting pins and the case is minimal, some third-party straps could also be too thick to comfortably match, particularly if they’re of the single-piece or pass-through selection.
The top-links of the bracelet on the 40mm model of the Tutima M2 Seven Seas S flare out to 25mm with a purpose to create an built-in look with the case, whereas the following hyperlinks provide a slight taper right down to 21mm the place they connect with the clasp. Though I might have personally most popular to have a bit extra of a taper given the 40mm case dimension of the watch, the precise bracelet itself is kind of strong and leaves little to be desired. That includes a very strong development and single-sided screws for the detachable hyperlinks, the bracelet is accomplished by a machined folding clasp that includes a double push-button launch, 4 holes of micro-adjustment, and an extra fold-out wetsuit extension system. Moreover, whereas the overwhelming majority of the bracelet is brushed, the edges of the hyperlinks obtain a high-polish end to match the polished surfaces on the edges of the case.
Whereas the 40mm model of the Tutima M2 Seven Seas S presents the identical strong development and spectacular 500 meters of water resistance that defines the remainder of the gathering, its lowered case dimension and extra refined styling make it ideally suited to be the overbuilt diver you could comfortably put on in on a regular basis life. The built-in look of its bracelet lends itself to a noticeably extra elevated general aesthetic, and even supposing the Seven Seas S is greater than able to standing as much as critical diving use, it’s also a mannequin that will hardly look misplaced when worn on dry land in additional formal settings. With an official retail worth of $1,980 USD on a strap or $2,350 USD when bought on the bracelet, the 40mm model of the Tutima M2 Seven Seas S does initially appear barely costly for a diver powered by this known-quantity motion. Nonetheless, what you might be actually paying for here’s a very well-constructed case, together with a novel function-forward design that’s emblematic of Tutima as a model.
