STURMANSKIE, a brand with a lineage of space and military watches, is proud to announce the re-issue of its new "OKEAN" model, a chronograph originally manufactured for the Soviet Navy in 1976, with pre-orders now open.
Sturmanskie traces its roots back to the First Moscow Watch Factory, founded in 1930, and is a watch brand with a proven track record in aviation, military, and space. It is also known as the watch used in humanity's first spaceflight in 1961.
**The 1976 Naval Chronograph "OKEAN"**
In 1976, production began on the "OKEAN" model, equipped with the 3133 chronograph movement for naval officers. This wristwatch, featuring a telemeter (a function to measure distance using light and sound), was named "OKEAN" (Russian: Okean, English: Ocean) and became a legendary model that supported the Soviet Navy.
However, production ceased during the Soviet era, and the "OKEAN" disappeared, making the existing pieces very few. Due to its limited supply, it is now highly valued as a collector's piece.
This new model is a reconstruction of that rare watch, based on modern design and materials.
**The movement is not the 3133**
**3133 Movement**
In 1974, development of the chronograph began. A new mechanism was built, and the 3133 movement, the heart of the watch, was completed. The 3133 chronograph movement is no longer in production and is now a dead stock movement.
**31679 Movement**
The 50th-anniversary model features the even rarer 31679 movement, which includes a hacking function. This movement is installed in the new model.
**Differences between the 2019 "OKEAN" Chronograph and the 2026 Model**
The OKEAN chronograph produced in 2019 was a 316L stainless steel bracelet model with an inner rotating bezel. This time, the inner bezel function has been eliminated, and it features a titanium case.
**Actual OKEAN Caseback**
The caseback is engraved with "1976-2026," indicating its 50th anniversary, and a serial number.
**Evolution through Design Review**
**2026 50th Anniversary Model OKEAN**
This model has undergone a review of its conventional specifications to improve visibility and overall perfection.
**Telemeter Scale**
Adoption of a fixed bezel (Arabic numerals at 12 o'clock) Elimination of the crown for inner bezel operation Optimization of the telemeter scale
Re-positioned minute scale Enlarged and three-dimensional indices Deepened sub-dials + concentric finishing
Reproduction of original hands
Metallized dial (silver/blue)
This achieves visibility and balance suitable for modern use while maintaining a classic design.
**Modern Specifications with Titanium Case**
The case material is titanium. It is lightweight yet highly durable, and the combination of hairline and polished finishes gives it a luxurious feel.
**World Limited to 200 Pieces - Pre-orders Open**
This model will be produced in a world limited edition of 200 pieces. There are no plans for re-production, making it a completely limited model.
Pre-orders are currently being accepted and will close once the planned quantity is reached.
The selling price is 297,000 JPY (tax included) *Price may change due to currency fluctuations.
As a model with a titanium case, limited to 200 pieces, and a rich historical background, the pricing balances collectibility and practicality.
**"OKEAN Revived in the Modern Era"**
This model is not merely a re-issue; it is a fusion of Sturmanskie's cultivated:
Design philosophy as a military watch Functionality as a chronograph Design adapted to modern times
This is a single piece that embodies these elements.
