Movement of the Subdelta Periscope

The rugged Russian automatic 2624 movement has already proven itself in many SUBDELTA Periscope watches.

The dial is cut into two hemispheres, where the upper one represents the nightly hours (18:00 - 06:00) and the lower one are the daytime hours (06:00 - 18:00). Its colors derive from the ones used on the hull of Holland's Walrus submarine class.

Subdelta Periscope Dial making

The dial has a layered (sandwich) construction, where the lower dial is filled with orange and white Swiss Super-LumiNova and the upper dial is cut through to obtain texture.

The crosshair on the dial resembles a submarine's periscope and - like the hands, numerals and indices - is lit by night due to the use of Swiss Super LumiNova.

Of course, twin AR-coated sapphire crystals are used to diminish glare and to give a clear look on both the dial and movement. All engravings are done by a laser and the custom-made crown shows the bearer's personal build number.

Technical details

Modified and updated movement: The Periscope is equipped with a Russian-made and proven 2624 automatic movement, which now has no minutes and seconds, and is handcrafted with Côtes de Genève, dorage noir and pear and has a bespoke winding rotor. It can be hand-wound as well.

Case material and construction: All parts of the Periscope's case are hand crafted from grade 5 titanium, being the highest grade of this exquisite material due to its lightness and hardness. All titanium used at SUBDELTA is milled, finished and decorated in the Netherlands. The industrial-looking bead-blasted finishing of all hardware is a statement in itself of what's being housed inside. The SUBDELTA case has the firm's DNA etched in bold yet simple lines, its distinctive shape being an evolution of the P1lot One with additional refinement.

Strap and drilled lugholes: The handmade leather straps by dutch artisan 7T2Straps.com are attached to the case using solid bars. The case has been drilled with a very high degree of accuracy on an extremely hard material. Bergeon is included with the straps at home.SUBDELTA Periscope handbuilt titanium Dutch watch

Crystal caseback: The matching grade 5 titanium screw down caseback is rated waterproof for 60 meters (6 atm) when shut with strategically positioned rubber gaskets. The sapphire crystal has been anti-glare treated on the inside, so the nicely decorated movement can be enjoyed with minimized reflections. The watch is individually numbered and details are laser etched into case and case back. SUBDELTA Periscope

Personalization: Each SUBDELTA has a meaningful date engraved between the lower lugs (ie up to 6 numbers) as a free option. The unique build number is laser-engraved on the outside of the crown as a constant reminder of the unique quality of the particular timepiece.

The crown: The bespoke titanium crown has been designed in-house and has been sourced by the best Swiss crown maker. It is positioned on the right side of the case for easy operation.

Bespoke tang buckle: The handmade tang buckle is also made out of bead-blasted grade 5 titanium. The profile of the buckle is hand-bent to follow the curve of one's wrist perfectly. To round it off, the SUBDELTA logo is laser-engraved on top of the buckle.

Twin anti-reflective sapphire crystals: SUBDELTA sources and watches with the best available sapphire crystals on both sides. The choice of anti-reflective coating on the inside is deliberate as the coating is more prone to scratching. This coating has a slight violet blue-purple hue, which can be seen when moved around in direct light conditions and gives the crystals a nice touch.

Sandwiched dial setup: The Periscope uses a sandwich dial, with the upper dial featuring intricate cut outs of the markings and the lower dial sporting the highest grade C1
