Featherlight Precision: Oceaneva Tempus Pure Classic Dress Watch SW210 Grade 5 Titanium

Finding a genuine dress watch that combines a Swiss hand-wound movement, aerospace Grade 5 titanium, and 200m water resistance usually requires a hefty five-figure investment.

Currently offered at an astounding special pre-sale price of £525 (down from an RRP of £1,389) ahead of its late October 2026 release, this limited-edition timepiece brings purist Swiss horology and extreme specs into an extraordinarily accessible price bracket.

Grade 5 Titanium Architecture & Featherlight Ergonomics

Named “Tempus Pure” from the Latin for time and a nod to its hand-wound heart, the watch makes an immediate impression on the wrist—or rather, a lack of one.

Weighing a featherlight two ounces (approx. 56 grams) total, the 42mm case is crafted from aerospace Grade 5 titanium.

This high-grade alloy is 45 per cent lighter than stainless steel, significantly harder, 100 per cent hypoallergenic, and completely impervious to saltwater corrosion.

Despite its elegant 10.46mm slim profile, the Tempus Pure houses a screw-down crown and a reinforced caseback, delivering a staggering 200-metre (20 ATM) water resistance rating.

It is an engineering feat rarely seen on traditional dress watches, providing total peace of mind whether you are at a black-tie gala or an unexpected poolside dip.

Purist Swiss Hand-Wound Mechanics

At the heart of the timepiece beats the Swiss-made Sellita SW210-1 manual-wind calibre. By doing away with a bulky automatic winding rotor, the SW210-1 allows the case to remain exceptionally sleek while offering watch purists the tactile joy of hand-winding their timepiece each morning.

Operating at a high-beat frequency of 28,800 vibrations per hour (4Hz) across 18 jewels, it features a Nivaflex hairspring, shock absorption system, and a 42-hour power reserve.

“Combining a hand-wound Sellita movement, Grade 5 titanium, and 200m water resistance, Oceaneva delivers an unbeatable horological specification sheet.”

Because Sellita manufactures the SW210 on bespoke order cycles with six-month lead times, hand-wound Swiss dress watches are notoriously rare from independent microbrands.

Oceaneva displays the finely decorated movement through a sapphire exhibition caseback, complete with a sweeping seconds hand and a subtle date window at 3 o’clock.

Limited Edition Craftsmanship & Bespoke Detailing

Framed by a scratch-proof 1.8mm sapphire crystal with an internal anti-reflective coating, the light blue dial features applied relief numerals filled with Grade A Swiss BGW9 Super-LumiNova for brilliant nocturnal legibility.

The polished fluted crown is stamped with the brand’s signature Trident logo, matching the highly polished lugs, bezel, and Grade 5 titanium buckle.

Fitted with a supple brown Italian leather strap featuring a classic alligator pattern, each colourway is strictly limited to just 50 individually numbered pieces (XX/50) worldwide.
