Small in Size. Limitless in Expression.

Whether as a padlock watch, ring watch, or pendant watch, these miniature timepieces integrate seamlessly into jewelry, accessories, and creative objects — extending beyond the traditional wristwatch.
Our Slimtech 4¼''' caliber 1042 and 3¾ x 6''' caliber 1032 — the smallest watch movements in the world — empower brands to rethink scale, proportion, and placement, wherever time becomes part of the design.
Think Small. Design Big.
As renowned brands explore ever more creative expressions of time, ultra-compact watch movements are gaining renewed attention.
Ronda's smallest Slimtech calibers 1042 and 1032 – developed for minimal space – enable these jewellery-driven concepts without compromising horological integrity. Engineered for precision in extremely compact dimensions, the tiny movements offer:
• Proven reliability and performance in jewellery-scale formats

• Swiss Made quality for exclusive collections
Watchmaking is no longer confined to the wrist — and RONDA slimtech make these formats technically viable.
