OLLECH & WAJS OW Ocean Graph MkII 11/56 COSC Limited (Photo Watch)

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 — and was developed closely with the Norwegian freediver Siri Østvold. This collaboration of professional diving expertise and classic watchmaking results in an instrument that connects emotionally to the historic model while also offering tangible technical advancements.

Only 1x. No. 11/56 COSC certified. As photo watch. Like new, nothing wrong. From video & photography. 3 years warranty from purchase. On Perlon strap.

The very last limited COSC certified with limitation number 11/56 on the crown (see video).

Design from practice

What makes the MkII special is its consistent focus on real underwater requirements; collaboration with a competitive freediver ensured that controls, readability, and wearing comfort were designed not as theoretical wishes but as tested solutions. The watch thinks along: every display, every hand, and every click has been revised to be grasped in fractions of a second — an advantage that freedivers and professional users especially feel immediately.

Robustness and depth capability

The MkII delivers real depth reserves: with 1000 m water resistance and a massively screwed case made of 316L stainless steel, it is designed for extreme use and offers more than just looks. This technical substance is complemented by careful manufacturing focused on durability and tightness — not least a reason why the watch is considered a reliable tool under adverse conditions.

Dimensions and wearing comfort

The proportions are remarkably balanced: with a diameter of 39.5 mm and a 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 remains comfortable even during longer sessions and maintains the balance between presence and wearing comfort.

The multifunctional bezel

A special feature is the newly designed rotating bezel that combines Tide Tracking with a GMT function, a top-time countdown, and a 20-minute dive scale. This integration allows planning for ebb and flow, keeping track of world times, measuring the crucial three minutes before a competition dive, and precisely documenting the critical first 15–20 minutes of a dive sequence — a multifunctional tool that meaningfully supports a wide range of marine activities.

Dial, color and readability

The dial adopts a clear, functional concept: a deep blue with contrasting orange accents ensures immediate recognition, while the hands and indices are designed in bright green and cream tones with Swiss Super-LumiNova® to provide precise orientation even in low light. This color and luminescence scheme is calibrated to work reliably underwater as well as in murky daylight on the surface.

Drive and precision

At its heart beats the custom Soprod Newton P092, an automatic caliber with 4 Hz and about 44-hour power reserve, designed for stable performance under stress. The first 56 numbered models are delivered as chronometers; furthermore, an official COSC certification is planned as an option, underscoring the brand's ambition to combine highest precision with durability.

Straps and adaptability

The MkII comes standard on a handcrafted blue Perlon strap, offering combination comfort and water resistance; additionally, three distinctive alternatives can be added: the historic S-Type Mark II “Beads-of-Rice” steel bracelet, the finely linked M-Heritage mesh, and the striking orange FROGMAN rubber with practical engraved scales and tables. These strap options transform the watch from a daily companion into 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 durability in its production and in independent tests; the Soprod caliber also carries a Chronofiable certification documenting its resilience. Ollech & Wajs offers a three-year warranty, a testament to the quality of workmanship and robustness of the construction.

Conclusion: Who this watch is made for

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