Product Overview

The THORN T023 V3.1 is the latest evolution of our vintage-inspired dive watch. While preserving the classic proportions and character of the original T023, V3.1 introduces two new dial colorways and a newly upgraded bracelet with a tool-less link-adjustment system.

The upgraded bracelet retains the same familiar exterior design, while the internal structure allows selected links to be removed and reinstalled without screwdrivers or traditional bracelet tools. This makes bracelet sizing quicker and more convenient.

The adjustment structure follows the same proven design already used on our T003, T004, T005 and SHY036 models, although the external bracelet design remains specific to the T023.

Designed for enthusiasts who appreciate classic dive watches, the T023 combines timeless styling with modern reliability. Every detail has been carefully refined to create a watch that maintains its vintage character while offering improved everyday usability.

Built with a 316L stainless steel case, domed sapphire crystal with inner AR coating, and 200M water resistance, the T023 is equally suitable for swimming, recreational diving, and everyday wear.

Most variants use the PT5000 high-beat automatic movement, operating at 28,800 vibrations per hour. A Black dial / BGW9 lume / SW200 movement variant is also listed; please check the selected option before ordering.
