OLLECH & WAJS OW Ocean Graph MkII

The Ocean Graph MkII opens a new chapter in the history of ambitious dive watches: it combines the robust tradition of the 1968 original with a contemporary, practical approach — developed in close collaboration with Norwegian freediver Siri Østvold. This synergy of professional diving expertise and classic watchmaking craftsmanship results in an instrument that emotionally connects with its historical predecessor while also offering tangible technical advancements.

Design from Experience

What makes the MkII special is its consistent focus on real-world underwater requirements; the collaboration with a competitive freediver ensured that operating elements, legibility, and wearing comfort were conceived not as theoretical desires, but as tested solutions. The watch anticipates needs: every display, every hand, and every click has been re-engineered to be readable in fractions of a second — an advantage particularly felt by freedivers and professional users.

Robustness and Depth

The MkII offers genuine depth reserves: with 1000 m water resistance and a massively screw-down case made of 316L stainless steel, it is designed for extreme use and offers more than mere aesthetics. This technical substance is complemented by careful manufacturing that prioritizes longevity and impermeability — not least a reason why the watch is considered a reliable tool in adverse conditions.

Dimensions and Wearing Comfort

The proportions are remarkably balanced: with a diameter of 39.5 mm and a case height that combines robustness with everyday wearability, the MkII sits solidly on the wrist without dominating. The finely brushed case and ergonomic profile ensure that the watch is comfortable to wear even during long sessions, striking a balance between presence and comfort.

The Multifunctional Bezel

A special feature is the re-imagined rotating bezel, which combines Tide Tracking with a GMT function, a Top-Time countdown, and a 20-minute dive scale. This integration allows for planning tides, keeping track of world times, timing the crucial three minutes before a competitive dive, and precisely documenting the critical first 15–20 minutes of a dive sequence — a multifunctional tool that meaningfully supports various maritime activities.

Dial, Color, and Legibility

The dial adopts a clear, functional concept: a deep blue with high-contrast orange accents ensures immediate readability, while the hands and indices in light green and cream tones are coated with Swiss Super-LumiNova® to provide precise orientation even in low light. This color and luminescence scheme has been adjusted to function reliably underwater as well as in murky daylight on the surface.

Movement and Precision

At the heart of the MkII beats the custom-made Soprod Newton P092, an automatic caliber with 4 Hz and approximately 44 hours of power reserve, designed for stable performance under stress. The first 56 numbered models will be delivered as chronometers; furthermore, official COSC certification is an optional extra, underscoring the brand's ambition to combine the highest precision with durability.

Straps and Adaptability

The MkII comes standard with a handcrafted, blue Perlon strap, offering comfort and water resistance; additionally, three distinctive alternatives can be added: the historical S-Type Mark II “Beads-of-Rice” steel bracelet, the delicate M-Heritage Mesh, and the striking orange FROGMAN rubber strap with practical, embossed scales and tables. These strap options transform the watch from an everyday companion to a specialized instrument — depending on the area of use and personal style.

Manufacture, Testing, and Warranty

Manufactured in the Swiss Jura region, the MkII has been tested for longevity in its production and in independent checks; the Soprod caliber also carries a Chronofiable test, documenting its resilience. Ollech & Wajs offers a three-year warranty, a testament to the quality of workmanship and the robustness of the construction.

Conclusion: Who this watch is made for

The Ocean Graph MkII is aimed at individuals seeking a serious, functional dive watch — be it the professional freediver who needs precise preparation and legibility, or the demanding enthusiast who values historical heritage and modern technology. With its combination of a multifunctional bezel, high water resistance, and thoughtful ergonomics, it is less a fashion statement and more a powerful tool that confidently holds its own both underwater and on land.
