WORKS Vintage Heuer 1/100 Decimal Mechanical Stopwatch Side Slider Ref 401.213 For Sale

Vintage Heuer 1/100 Minute Decimal Industrial Stopwatch

## Reference Family: 401.213 | Caliber: Valjoux 7700 | Swiss Made

Up for sale is a rare, scarcer configuration of a vintage 1970s Heuer mechanical industrial stopwatch. This is a highly sought-after variant featuring both a decimal 1/100 layout and a manual side \"time-out\" lock slider mechanism.

Designed historically for industrial engineering and time-and-motion efficiency studies rather than sports, this model was produced in significantly lower numbers than standard 60-second track timers.

### Key Features & Specs:

* **Brand:** Heuer (Pre-TAG era)

* **Dial Layout:** Decimal Timer (1/100 minute divisions on the outer track) with an inner 0-30 minute register.

* **Side Slider Mechanism:** Includes the rare integrated left-side slider switch used to pause/lock the mechanical gear train for time-outs without resetting the main hands.

* **Movement:** Swiss manual-wind mechanical movement (Valjoux Caliber 7700 variant).

* **Case Size:** Standard 53mm case diameter.

* **Finish:** Rugged, glare-resistant dark textured matte casing.

### Condition Notes:

* **Functionality:** Fully tested and working perfectly. The main crown winds smoothly, keeps accurate mechanical time, stops cleanly, and snaps back firmly directly to zero. The side slider functions exactly as intended to lock/unlock the timing sequence.

* **Cosmetics:** In great vintage condition. The dial faces cleanly and is easy to read. [Insert any minor notes here, e.g., The crystal features some light surface scuffs from normal storage/use, and the case back shows light age-appropriate wear as shown in the photos.]

Please review the high-resolution photos carefully to assess the cosmetic condition for yourself. The chain lanyard pictured is included in the sale.
