The LUCA CH-1 Chronograph collection is constructed of the highest quality materials like 316L stainless steel, a legendary Miyota movement, and a genuine sapphire crystal. The CH-1 blends both extreme durability and flawless refinement, so you can wear it at the office or at the beach. The sophisticated brushed finish accessorizes beautifully. Finish the look with your choice of a high-quality band to add an element of style that’s all your own.
Our CH-1 Chronograph series is a fine men's watch made from expertly-sourced materials and assembled using modern workmanship and design. The BR-1 features a practical, easy-to-read dial with a simple, yet highly functional rotating bezel. Each watch is engraved with a unique serial number on the back plate and is delivered in a beautifully designed, heavy-duty watch box with a plush interior. In the box, you will find a selection of LUCA accessories, as well as the band of your choosing. The LUCA Chronograph is also available in the BR-1 series with a polished finish.
The Movement: The famous Miyota 0S20 movement can be found on some of the world’s most prestigious watches. This movement contains many precision parts, running at a frequency of 32,768Hz. It is considered one of the most robust and reliable mechanisms on the market.
The Case: The case of the CH-1 consists of three main pieces: A screwed on back, a top unidirectional bezel, and the case body. All of these parts are made out of high-grade (316L) polished stainless steel. The case is designed, and rigorously tested, to withstand pressures equivalent to 10- ATM (100 meters underwater).
The Dial: The look and feel of the CH-1 dial is inspired by historical chronographs. The markers and hands offer excellent luminescence, which can last up to 9 hours in total darkness. This is made possible thanks to LUCA’s incredible luminescence, which is one of the best non-radioactive luminescence technologies on the market today. The dial consists of two layers—the upper layer has a traditional raised “race track” design around the interior perimeter, and the primary layer is slightly textured with three sub-dials engineered directly into it.
The Watch Bands: Choose your CH-1 strap from several LUCA styles. The CH-1 is compatible with our 22 mm watch bands. We are always designing new bands. Currently, we offer watch bands in:
