Eldon Watches | Modular Watch

Fully-interchangeable Modular Watch .

The Eldon modular watch allows the user to fully customise their design from a variety of removable bezel, watch body, strap and dial designs. Based around a Swiss Ronda quartz movement, the watch is produced from brushed stainless steel and water resistant to 50m.


The technical design of the watch was built around the sourced Ronda movement and incorporated watch components. The modular aspect of the design posed an interesting technical challenge, and specific care was taken to maximise the size the removable bezel and ensure ease of disassembly by the user.
