ADVANCED DIVING TIME
LITTLE BIG INNOVATIONS
You can adjust the dive start time just like in any Diver's watch by locking the bezel with a simple crown push at the beginning of the dive.
But you can also, underwater, set a new start time, for example, the decompression time. And let me tell you, this feature is incredibly useful.
The FROG 300-SUB features a special interior unidirectional bezel that is 100% protected, allowing for precise control of dive times. It incorporates high-quality luminosity, combined with appropriately sized indices for optimal readability. Furthermore, the bezel has 60 clicks, not 120, aligning with dive tables for accurate decompression stop calculations. An uncommon feature is that the unidirectional crown on the Diver's bezel allows for adjustments underwater.
The ability to reposition the reference point to calculate, for example, the time for a decompression stop is a superb advantage !
The case is completely waterproof up to 300 meters (1,000 ft) deep, thanks to a new design of Dupond Teflon seals rings in 'T' shape, replacing conventional O-ring seals and ensuring unprecedented watertightness. It's similar to the iconic Seiko Tuna Emperor 1,000-meter watches that feature L-shaped seals. These seals work in a 3D manner, creating two distinct compression zones, effectively preventing water molecules (H2O) or helium from penetrating the interior under external pressure (and vice versa, preventing them from escaping). Additionally, our FROG300 ISO6425 Diver's watch for saturation diving also incorporates a Helium release valve, providing 100% secure protection to the movement.
The FROG300 is a pro saturation Diver's watch, and for him the Helium valve it's not necessary, but man, it looks awesome!
DIVER'S + GMT
The solvent and innovative NH34A11J caliber with 24 jewels, beating at 21,600 vibrations per hour, is confidently signed by TMI JAPAN (Seiko Instruments SII). It features a hacking seconds function, manual winding capability, and a power reserve of 41 hours. This caliber allows us to integrate a useful feature into our Diver's watch—a dual independent GMT time zone, indicating whether it's day or night in the other city (it's 24-hour format). You can keep track of both your home time and the time in the city where you're enjoying your epic experience (or doing what you love). Some ISO-certified Diver's watches also offer this function, but very few combine the Titanium-Divers WR300m and GMT trio. Moreover, each NH34A movement in the FROG300 is adjusted in-house to achieve a top-level timekeeping precision range of +15 / -10 seconds per day.
DIVER'S + GMT
Caliber doubly protected by a sub-structure that isolates it
The automatic NH34a caliber with GMT function, built in Japan by TMI/Seiko Instruments (SII), features the Diashock system that protects the mechanism against shocks and falls. But at OX Oceanix, we've taken it a step further by working on the Cushion, both in terms of design and hardness (density), creating additional protection against unintended minor drops, so your watch keeps running like new—perfect!
WITHIN THE MARKET OF WR200/300-METER TITANIUM DIVER'S WATCHES, VERY FEW UTILIZE GRADE 4 TITANIUM (ALTHOUGH THE TAG AQUARACER SOLAR TITANIUM, PRICED AT 3,100 EU, DOES). THE USUAL CHOICE IS GRADE 2 TITANIUM, WITH SOME CASES INCORPORATING ADDITIONAL SURFACE HARDNESS TREATMENTS, AS PRACTICED BY CITIZEN WATCH.
The OX OCEANIX FROG300 exclusively uses advanced materials in watchmaking. It features Grade 4 titanium with a Sandblasted and/or Black DLC (Diamond-Like Carbon) finish on the bezel and case, and IP gold titanium on the caseback (back closure of the watch), or a ceramic coating on the DIVE crown (providing enhanced visual perception and resistance), signed by Cerakote USA. It includes an incredibly durable Sapphire crystal with double curvature and excellent transparency, topped with a blue anti-reflective (AR) coating on the inner surface. The functional screws are made of black DLC-treated 916L stainless steel. The high-density fluoroelastomer strap, which is flexible and highly resistant, or the two-tone Grade 4 titanium bracelet (optional accessory), complete a Diver's watch that boasts excellent external resistance and hardness, prepared to withstand the test of time like few others.

A BEFORE AND AFTER IN ECCENTRIC 'XL' COMFORT
MORE WATCH DETAILS
The Oceanix FROG watches are not small with their 45 mm diameter and 15,8 mm height, but their eccentric case, extreme lightness, the interior position of crowns, and the Lug-to-Lug minimal distance design make it one of the most comfortable large-sized watches on the wrist - very likely - of all time. With a total weight of just 112 grams (with strap and clasp), this instrument watch will adapt incredibly to you - thanks to its carefully designed underside - whether you have large, medium, or even small wrist. Additionally, its high-resilience fluoro elastomer strap will provide you with an extra level of soft comfort and flexibility. It is hypoallergenic (just like titanium), and with its unique textured relief for moisture and ventilation on the inside, it will also offer you extra comfort - something you will greatly appreciate in your day-to-day activities. And that's not all: Its specially designed clasp allows you to do two things. Firstly, you can micro-adjust the strap for summer/winter changes, and secondly, you can quickly adjust the watch on top of any wetsuit or technical jacket using the two side pushers. You can only remove it with the 'LOCK' safety button.
The FROG300 stands out as a top-tier Diver's watch thanks to its pinnacle details. It's not just its extreme durability or added vital functions that position it as a great "diver's lord" for saturation diving – it's the smallest details that demonstrate a high level of commitment to maximum quality and perfection. Examples such as its time and GMT adjustment crown topped with a titanium IP (ion-plated) threaded insert in gold, or its low-relief engravings on the case, showcase this dedication. The intricate dials and applied indices are another prime example of the precision and construction technology employed in each of these instrument watches. The meticulously crafted hour hands ensure clear and dynamic readability, far beyond what is commonly known. The FROG300 is simply unique.
