The Summit Collection: A Strong First Step for New Brand Earthen

Earthen Company is one of the freshest names to enter the watch market, founded in Hong Kong in 2025 by a group of passionate collectors and enthusiasts. Co-founder Jonathan Chan, also a key figure behind The Horology Club, explains that the team approached this project as collectors first, not as traditional watchmakers. 

The result is a debut that doesn’t chase trends but instead offers something unique, a series of ceramic, field- and pilot-inspired watches at an accessible price point. With the launch of the Summit Collection, it’s clear Earthen intends to make an impression from day one.

Introducing Delma Unveils the 1924 Tourbillon in Blue and Salmon

Expanding the brand’s tourbillon collection with striking new colors

Delma is a Swiss brand that has been producing high-quality, sophisticated watches for more than a century. Following last year’s centennial celebration, during which it released the 1924 Tourbillon, Delma returns with two new dial variations in blue and salmon.

The 41mm tonneau-shaped stainless steel case that is 14mm thick, featuring a raised sloped bezel and crown guard, showcasing a mix of brushed and polished finishes. A sapphire crystal with anti-reflective coating protects both the front and back of the case.

The blue and salmon dials enhance the aesthetic with a fine grains de riz guilloché pattern that shimmers under the light. The lozenge indices, nickel-plated palladium hands, and the upper tourbillon bridge with blued screws, all carried over from the previous edition, are now elevated by the new dial colors. Super-LumiNova BGW9 ensures legibility, even in low light. Positioned at 6 o’clock, the tourbillon rotates once every 60 seconds and also serves as a small seconds display.

Powering the watch is the hand-wound Caliber DT100.01, developed by Olivier Mory, a name recognized for creating accessible tourbillon movements. It beats at 21,600 vph (3 Hz) and delivers a remarkable 105-hour power reserve.

The movement boasts technical highlights such as a KIF shock absorber (resistant up to 5,000 G), and anti-magnetic protection of up to 2,000 Gauss, courtesy of a Glucydur balance wheel and Nivarox alloy hairspring. It is finished with a ruthenium treatment, perlageCôtes de Genève, and blued screws, all visible through the exhibition caseback.

Each watch comes on a three-link stainless steel bracelet with a wide central link, and a black calf leather strap is also included. Both versions are limited to just 25 pieces and are priced at CHF 12,900 / AED 57,600, a slight uptick over last year’s model.
