Evaluating Watches For Diving from Alpina, Davosa, and Hamilton

Alpina’s Seastrong Diver 300, Hamilton’s Khaki Navy Frogman and Davosa’s Apnea Diver Automatic choose to dive, nowadays they’re in the pool. During this comparative review from WatchTime’s March-April 2018 issue, we test these 3 sporty watches for diving to discover the way they perform swimming laps and jumping from diving boards.

A quick consider Davosa’s unconventional Apnea Diver Automatic, among the number of watches particularly created totally free divers, can make it apparent this very sports pursuit not just demands peak physical performance but in addition self-confidence and self-reflection.

Such as the Apnea, the extroverted 2016 edition within the Khaki Navy Frogman was created along with a global-famous apnea diver. In lots of other respects, however, the present edition in the Hamilton watch pays homage for that divers’ watch that arrived on the scene within the 1951 movie, The Frogmen, and elevated to obtain the initial Hamilton watch to elegance the enormous screen. And last but including, Alpina’s Seastrong Diver 300 can also be influenced by history but is a lot more understated inside the styling. This model may be the direct descendant within the Seastrong 10 inside the 1960s, that was water-tight to 200 meters when the first debuted.

The present Seastrong is water-tight to 300 meters, thats liable to bring up an “old” debate. The misperception the old saying “watertight to xxx meters” specifies the depth that the watch can securely descend is broadly circulated and chronic. In addition to, since almost no one dives having a depth of 300 meters, a watch that’s labeled “watertight to 30 meters” would appear to obtain appropriate for diving 30 meters underneath the surface. However, this assumption is completely wrong. Inside a couple of countries, another legal verdict now prohibits watch manufacturers from indicating the depth water tightness in meters only. The specific water tightness is dependent upon the quantity of water pressure this watch survived within the water-tightness test. For the Seastrong 300, what this means is 30 bar, i.e., the quantity of pressure exerted getting a 300-meter-tall column water or possibly inside a depth of 300 meters underneath the surface: hence, the specs in meters.

The depth in meters is printed across the Seastrong’s dial

Since the corresponding pressure in bar or ATM (atmospheres) is engraved across the caseback. The 3 watches within our test are water-tight but to several depths. The Davosa is water-tight to 200 meters, i.e., pressure resistant against 20 bar. The Hamilton can descend even so much much deeper: it stays water-tight one,000 meters, i.e., pressure resistant against 100 bar. Every one of these three watches can come along for almost any dive additionally to accompany its wearer for almost any dip within the pool. Unlike timepieces which are water-tight simply to 30 meters, i.e., pressure resistant against three bar, these watches can withstand the finish result water spraying within the showerhead or perhaps in the Jacuzzi’s massage jet as rapidly as they possibly can deal with a effective freestyle swimming stroke or maybe a leap headfirst immediately block in a 50-meter pool.

If you want to visit swimming individuals 50 meters underwater on one breath of air, your Apnea Diver Automatic is a great choice since the colored arcs across the seconds scale over the rim within the dial make sure it is easier to coach yourself to secure your breath and measure just how you're progressing. This scale is calibrated using the globally agreed-upon request free diving: 5 seconds of inhalation (proven in blue), adopted simply by a matter of seconds of holding your breath (the white-colored-colored-colored arc), and lastly 10-seconds of exhalation (suggested for red). And Davosa has imagined up an expedient mechanism for training on dry land: in case you unscrew the crown at 3 o’clock, you can eliminate the main situation within the container, switch open a hinged ring and stand this watch round the desktop like a miniature table clock. Freediver Nik Linder also integrated another practical detail towards the Davosa’s Apnea: minutes participate in the decisive role for technical all scuba divers, but seconds are essential for apnea divers. For this reason the seconds hands concerning this watch culminates in a elongated red tip that extends across and sweeps unmistakably within the seconds scale.

A extended red tip also defines the business finish within the seconds hands across the Khaki Navy Frogman, that was designed together with apnea diver Pierre Frolla. But unlike the Davosa model, the Frogman is appropriate for many diving-related purposes, because of the minutes calibrations for technical all scuba divers on its rotatable bezel, pressure capacity 100 bar for dives to great depths, along with an automatic helium-release valve for saturation diving. The Frogman blithely survived a boost in the ten-meter tower, along with the protected, canteen-style crown also survived a hard smack within the side from the pool. Nonetheless the big crown guard, that's adapted inside the one concerning this watch’s predecessor from 1951, can make it somewhat cumbersome to function the comparatively small crown beneath the protector.

The operating areas of our other two test watches are screwed lower. Handling the Davosa’s crown is demanding due to its position at 12 o’clock along with the rigid container underneath. The crown across the Alpina Seastrong includes a rubber ring and you'll be able to grasp, unscrew, operate, and screw shut again. The Seastrong is alright for swimming within the pool, nonetheless it lacks a couple of details that will qualify it a professional divers’ watch: for instance, an illuminated seconds hands to instantly disadvantage rm this wrist watch remains running and single-minute calibrations within the entire rotatable bezel. To provide credit where credit arrives, all the Seastrong’s scales are totally luminous, a detail that's rarely seen on divers’ watches. The downsides will be the hour hands along with the minutes hands aren’t easy to differentiate when asleep, and single-minute calibrations are missing across the dial as well as on two-thirds within the rotatable bezel. For wearers in the watch, therefore you goes swimming a couple of leisurely laps within the pool and perhaps preset your intended swimming time while using the rotatable divers’ bezel. Or maybe even chill at poolside or recline within the chaise longue across the lawn nearby.

Diving isn't any difficulty for Davosa’s Apnea

Its luminous double-digit figures, bold indexes, and broad hands are clearly visible, although swimming over the ft in the pool’s deep finish. The numerals, indexes, and also at work Hamilton’s Khaki Navy Frogman also glow at great depths along with a beautiful shade of blue. Should you appear for air, you’ll find Alpina’s Seastrong Diver 300 awaiting your self on a sunny day. This watch lately altered its outfit: it's been provided having a stainless-steel bracelet since 2017, nonetheless the tripartite construction within the double folding clasp has neither a divers’ extension nor a thief bracket. The rubber straps of three watches we tested also lack these traits, so they’re Suitable for swimming, whilst not ideal for professional diving.

Despite its nearly 45-mm-diameter stainless-steel situation, the Alpina looks comparatively unpretentious. It is also alone within our trio obtaining a transparent caseback, by which an aficionado can admire Sellita-based automatic Caliber AL-525. This movement is outfitted obtaining a unique rotor while offering its ideal time keeping performance when on its wearer’s wrist. Exactly the same fundamental caliber within the Davosa’s situation exhibits somewhat different rate behavior: it runs better overall, yet it's not well-balanced. That is hidden behind an enormous, fully threaded, screw-using the spine, which hermetically seals the nearly 43-mm-diameter stainless-steel situation. The container enlarges the general diameter in the watch having a hefty 46-mm that it is a real more massive impression. Immobile lugs along with the tall construction within the situation imply this watch ought to be worn by getting an nicely sized wrist.

Hamilton’s Frogman can also be created for individuals who've big wrists. The titanium situation isn’t only an impressively large 47.5 mm across, but it is also rather tall. It spreads a caliper’s jaws 16.12 mm. This height is among the tribute required by pressure capacity 100 bar. This watch is outfitted with Caliber H-10, we know of because the “Powermatic 80” and draws on an ETA C07.611. Since its name suggests, it amasses an 80-hour power reserve. It runs with perfectly-balanced rate values, so that it achieves while hidden behind an enormous screwed situation- back engraved obtaining a diving motif.

While small enhancements might be produced in many these 3 watches, Hamilton’s Frogman outdid its two competitors. It satisfies all of the needs from the divers’ watch apart from a thief bracket for the clasp along with an extension mechanism to elongate the strap. Davosa’s Apnea performed perfectly although it isn’t particularly created for diving, single-minute calibrations along its bezel is really a welcome addition. And Alpina’s Seastrong 300, a divers’ watch that continues this brand’s tradition, would take full advantage of a couple of modifications: the illumination along with the calibrations be effective on numerous Alpina’s other models.
