Our cases are produced in 3D-printed titanium grade 5, giving us the freedom to create shapes that conventional manufacturing cannot easily achieve. Each print is carefully validated before it enters our workshop for precision machining and hand finishing.

After printing, every case is individually calibrated and milled. Critical fittings for the movement, crystal, caseback and crown are machined to tolerances down to one hundredth of a millimetre.

The case, crown and buckle are filed, sanded and polished by hand. This patient process sharpens the architectural lines and gives every watch its individual character.

Movement components are shaped in-house with traditional machinery and precisely made templates. This combination of manual control and precision machining creates the distinctive architecture of our calibres.

Every visible movement component is finished by hand. Frosted surfaces, polished bevels, contrasting textures and carefully finished screws create depth while reinforcing the architectural design.

Most dials are made in-house, from machining the blank to creating relief, texture and colour. We combine traditional tools with laser technology, precious-metal plating and titanium anodisation to achieve durable, distinctive finishes.

Our hands are cut from carefully selected metals and finished individually. Generous polished bevels and contrasting surface textures make them legible, light and unmistakably Holthinrichs.

Our watchmakers assemble, regulate and test every timepiece in-house. Each watch passes a final quality control and is delivered with its individual measurement results.

The finished watch is presented in a compact nutwood box, handmade in the Netherlands and suitable for travel. Every timepiece includes a two-year warranty and continued service support afterwards.
