Oceaneva Tempus Pure pairs Grade 5 titanium with a hand-wound Swiss movement

Oceaneva is best known for watches built with depth ratings and durability front of mind, but the Tempus Pure shows a quieter side of the brand.

This is its first titanium dress watch with a manual-winding movement, and it keeps the formula deliberately simple without abandoning the practical toughness Oceaneva buyers tend to expect.

At a glance

A dress watch with tool-watch instincts

The Tempus Pure marks a clear shift in tone for Oceaneva, moving away from the brand’s familiar overbuilt dive and tool-watch language.

That doesn’t mean it has become fragile.

The case is water resistant to 200 metres and uses a screw-down crown, which gives the watch a level of everyday security rarely associated with slimmer dress-leaning designs.

At 42mm in diameter, the Tempus Pure is still a watch with presence rather than a tiny formal piece.

The more notable figure is its 10.46mm thickness including the crystal, helped by the absence of an automatic rotor.

Grade 5 titanium keeps the case light and crisp

Oceaneva has chosen Grade 5 titanium for the case rather than the more common Grade 2 alloy often seen in watchmaking.

Grade 5 is harder, more scratch resistant and more receptive to refined finishing, including brighter polished surfaces that are difficult to achieve on softer titanium.

The result is a watch that weighs just 57g while still offering the strength and clean case definition expected from a modern titanium piece.

That low weight matters on a leather strap, where a larger case can otherwise feel top-heavy.

Here, the Tempus Pure should wear more easily than its 42mm diameter might suggest.

Six dials, including three full-lume options

The dial layout is intentionally pared back, with Arabic numerals sitting inside a railway minute track and leaf-shaped central hands doing the timekeeping duties.

A borderless date aperture at 3 o’clock adds practicality without making the display feel crowded.

Oceaneva is offering six dial choices across standard and full-lume executions.

The conventional options include black enamel, light blue enamel and a blue sunray burst finish.

The full-lume versions come in orange, BGW9 blue and X1 green, giving the Tempus Pure a more playful edge than its dress-watch description might imply.

Each dial can be paired with either a black or brown Italian leather strap with an alligator-pattern finish, creating 12 references in total.

A hand-wound Sellita calibre inside

The Tempus Pure is powered by the Sellita SW210-1, a manual-winding Swiss movement running at 28,800 vibrations per hour.

It offers a 42-hour power reserve and drives hours, minutes, seconds and date.

The choice of a hand-wound calibre is central to the watch’s character.

It keeps the case slim and adds a more tactile daily ritual, with winding handled through the knurled crown at 3 o’clock.

For a microbrand watch at this price point, the combination of a Swiss manual movement, Grade 5 titanium and substantial water resistance gives the Tempus Pure a strong technical argument.

Details & Specifications

The Tempus Pure will likely appeal to buyers who want the lightness of titanium and the engagement of a hand-wound movement without giving up daily-wear resilience.

It isn’t a traditional dress watch in the most delicate sense, but that’s precisely what makes it feel relevant for modern use.
