Deepwave Diving Watch

With the G44 Deepwave, a true masterpiece has been created - robust for daily use under adverse conditions and at the same time so elegant that the watch accompanies the wearer in everyday business life. However, it only reveals its true potential when you take it into the water.

Guinand G44 Deepwave

The Ocean Floor

The ocean floor is a world so alien to us humans that it might as well be on another planet. We know very little about what lies in the deepest depths of our oceans, about the trenches, canyons and mountains that exist there, and about the creatures that call them home.

Bathymetry involves mapping the topography of the seafloor and documenting it in bathymetric maps that show the characteristic contour lines. These lines are also stylized on the solid back of our diving watch.

The Watch

Guinand has a long tradition of building robust watches for aviation, science and maritime applications. This know-how has flown into our G44 model family. Perfect readability day and night, extreme pressure resistance and robustness characterize this sports watch.

The Dial

For best readability, the G44 is equipped with a matt black dial and applied luminous indices. In contrast to the luminescent color usually applied by a printing process, we use hour bars made entirely of luminescent ceramic.

The significantly larger luminous surface and the C3 Grade X1 luminous pigments used result in optimal readability day and night.

Readability at night

For both the hands and the dial, we use what is currently probably the most powerful luminous pigment, SuperLuminova© Grade X1 C3. For the hour markers, we have hour markers cast from luminous ceramic in our molds in Switzerland. These are riveted onto the dial.

To make it easier to distinguish between the hour and minute hands, we not only made the hour hand significantly shorter than the minute hand, but also filled it with green luminescent pigment. The minute hand, which is important for diving advances, the main marking and the second hand are filled with blue afterglow luminous pigment.

The Movement

For the G44, we are using a movement of the Swiss family-owned company Sellita, based in La Chaux-de-Fonds. The SW200 is produced since 2008 and considered as well-engineered, the basic construction dates from the year 1982. Sellita, manufacturer of watch movements, supplies Guinand with the movement for this watch in the “TOP”-version, decorated with Perlage, Geneva stripes and blued screws.

At Guinand each of these movements is regulated once again in 5 positions before the final control of the watch ends with an accuracy test of several days.

The Watch Case

This sports watch is clearly a Guinand model and the typical DNA of the brand is clearly recognizable. For use in and underwater, we have designed the housing for a pressure resistance of 30 bar. For maximum water resistance, the G44 is equipped with our FKM-R sealing system for the triple sealed crown and base. The bezel can be rotated unidirectionally in minute increments and is made of stainless steel with a hardened surface.

The inlay is labeled according to the specifications of the diving DIN. We manufacture the inlay from break-resistant, black hard-coated stainless steel. The lettering is milled out. For the front glass, we use anti-reflective coated sapphire crystal that is curved on both sides.

The case technology

Screw-down crown with triple sealing system and flank protection enable a reliable pressure resistance of 30 bar. FKM-R sealing system for crown and back.

Crown tube screwed to the center part of the case, diver's bezel made of stainless steel, tempered to over 1000 Vickers and mounted on 3 encapsulated ball locking systems in the case.

Size comparison

Based on the size values, it is not easy to decide whether the watch fits the wrist, or whether it is too big or too small. To make your decision easier, we have mounted the watch on three different wrist widths that correspond to the usual sizes.

How to determine the correct strap length?

Please note that the wrists shown can only give you an approximate impression of the watch on your wrist, as the shape of the wrist is different for everyone, even if they have the same circumference.

The Strap

Metallband Typ H Matt SVSS

Metal strap Type H Matt SVSS

Sports watches require special straps - robust, comfortable to wear and, of course, just as high-quality as the watch. We recommend our solid stainless-steel bracelet Type H Series II with quick-change system for tool-free assembly/disassembly with a standard clasp or our SVSS* clasp with tool-free strap length adjustment by up to approx. 1.7 cm in 11 steps using a button concealed in the clasp cover.

Alternatively, you can use our waterproof Cordura® fabric strap or one of our rubber or leather straps.

* Quick release safety clasp SVSS with 2 independently locking push buttons for increased security against unintentional opening of the clasp
