This is Ginault 30.4mm Dome Crystal. It’s from the best supplier in the country. Albeit Ocean-Rover 181070GSLN is a Rolex Submariner 16610 homage. We did not want to take the shortcut and put an aftermarket 25-295-C, Rolex’s signature crystal with a cyclops a 3 o’clock on it.
We want to bring something sensational, something nostalgia to Ocean-Rover’s owners. Thus we came up with Ginault 30.4mm Dome crystal. It is made of corundum, the second hardest material next to diamond.
In the designing phase, we also wanted to make sure Ginault Ocean-Rover and any of our future models equipped with 30.4 Dome crystal to withstand the extreme water pressure while being worn under water.
By increasing the thickness of Ginault 30.4 Dome crystal from 1.8mm to 3.1mm, plus with the computer aided design software calculated the surface curvature, the maximum depth Ginault 30.4 Dome crystal can withstand is 1,220 meters underwater in computer simulations. However, the actual testing equipment our supplier has could only simulate water pressure up to 1,000 feet. Nonetheless, Ginault 30.4 Dome crystal’s real world test in our supplier’s testing chamber went with flying colors at 1,000 feet.
Until we conduct our tests in a more sophisticated institute, we put 1,000 ft / 300 m on the face of the watch.
For those tactically aware members, unlike Rolex 25-295-C, which has quite a direct light reflection point, we specifically designed Ginault 30.4 Dome with almost no direct light reflection point. Slap on the Nato strap this watch won’t become an object exposing your tactical positions under a bright sunlight in the open field.
We believe if a diver’s watch has a soul, it must dwell in the luminous indicator on the bezel. The quality has to match with other parts of the watch. From the same supplier of our crystal, the luminous indicator is also made of corundum.
We set the corundum indicators one by one on rodico, apply luminescent material carefully in each one of them the same way we do on our forged hour markers, then hard pressed them in the cup shaped holders made of german silver along with the aluminum bezels.
The Watch Face
Gold Sand Lume
An homage should never be just a lookalike or a replica. The makers of an homage watch should bring value, taste, and innovation to the classics.
We have heard of the legend of a luminescent material that is not a product from the Swiss RC Tritec, the lume company, and is so expensive only the top antique clock and pocket watch restorers could afford and would be interested in using on their masterpieces. We travelled far to acquire this unique luminescent material.
Ginault Gold Sand performance is comparable to pure Superluminova C3 in terms of burst and longevity. After a full charge, the initial high lume will fade gradually in 15 or so minutes. The low lume will remain visible in a pitch black room for 12 plus hours.
The High Gloss Enamel Dial
Dial creation in the process of producing a watch has its own special pedigree. A dial not only represents the identify of a watch, it is also what connects the movement, the hands, and the functions of the watch to the wearer. It not only reads time, it also gives the final finished touch of the overall aesthetic and balance of the unit.
Creating a high gloss enamel finished surface with perfectly forged, angled, and finished hour markers take nothing less than a true craftsman with the sum of many skills calling for both great expertise, decades of experiences and know how in the making of a single perfect dial.
Looking around, only a handful horological titans use high gloss enamel dials with forged, mirror polished hour markers in their product lines. The craftsmanship and cost required in making this kind of dial post as a barrier for many watchmaking companies to enter the world of “Haute Horology”. In fact it is rare to find a watchmaking company like Rolex which controls in-house all the aspects of dial creation, from design to production.
Luckily along the way we were introduced to a master dial maker in the United Kingdom who has worked for a famous Swiss watch company specializing in dial production to help us realize this dream of creating a top of the line classic Submariner 16610 homage dial.
Enamel is an opaque substance that is a type of silicon. After solidification in high temperature, it produces uneven cracks and tiny apertures that look like scratches or flaws on the dial. Only through years of restless practices, can we present to you the almost perfect, high gloss enamel dial in deep black.
When we were first introduced to our dial maker, we did not possess much knowledge about the differences in forged hour makers. Looking across the market it is not hard to find that only a handful of brands have forged hour markers on the dials. They all look the same right? But truth to be told devil is in the detail. What the difference is between an artisan made hour marker vs a production line hour marker is hard to explain by words. It is more of an experience. Have you ever noticed when you turn your wrist over to look at time some watches just don’t give you that pop, and on the other hand the few elite makers’ watches reveal otherwise.
Forged, Mirror Polished Hour Markers
The secret lies in the finest details of the way the blank hour marker is forged and shaped. We encourage members to take a look of Ginault’s hour markers with a loupe. Another important step is how the hour marker was polished from the blanks. Only through arduous polishing by hand each hour marker can then have the shine, the reflections of light, and that polished uneven deformation on each corner of the forged hour marker brought to life.
