Designed by Markus Eilinger, the ALFEX AQUATEC “31” is a sporting collection designed for people who live their lives with determination and speed. “31” represents a milestone in the history of the ALFEX brand as the company celebrates its thirty-first year of making finely designed watches. The words of its name indicate the characteristics of the watch; speed and strength combined with sport and the latest technology.

The AQUATEC collection features a Swiss-Made quartz movement with a calendar in the 3 o’clock position. The chronograph version boasts a Big Date calendar in the 12 o’clock position and has a synchronized changeover from 31 to 1. All feature sapphire crystals. Choices include Diver or Tachometer versions with either steel or rubber bracelets enhanced by a rugged déployant clasp.

All dials and hands have Superluminova material for easy night-time vision. Anti-allergic high polished stainless steel construction including three-piece cases and screwed-down crowns allows for water resistance of up to 10 ATM. The retail sale prices range from Sfr 460.00 to Sfr 595.00, for the chronograph models.
