The Tissot caliber 782.1 is a manual-winding mechanical movement and a variant of the Tissot caliber 782, produced during the 1960s and 1970s. It was part of the brand’s 780-series of compact in-house calibers, designed primarily for ladies' watches and elegant mid-size dress watches. The “.1” suffix indicates a first-generation technical update—common practice in Tissot’s movement development at the time to signify improvements in reliability, component layout, or serviceability.

Overview of the Caliber 782.1

The Tissot 782.1 was created to meet the demand for slim, reliable mechanical movements that could fit into small and ultra-thin cases. It shares most of its architecture with the base 782, but may differ slightly in:

• Bridge design

• Shock protection system

• Component tolerances or geartrain refinements

These adjustments were likely introduced to improve production consistency and after-sales serviceability while maintaining the same time-only functionality.

Technical Specifications

• Type: Manual winding

• Functions: Hours and minutes only (no seconds hand in most cases)

• Jewels: 17

• Frequency: 18,000 vibrations per hour (2.5 Hz)

• Power Reserve: Approximately 40 hours

• Diameter: ~17.2 mm (7¾ lignes)

• Height: ~3.0 mm

• Shock protection: Typically equipped with Incabloc

• Finishing: Industrial matte or brushed finish; Tissot-signed bridges, often gold-toned or nickel-plated

The 782.1 is built for reliability and simplicity, offering a long service life with minimal maintenance when properly handled.

Watches Featuring Caliber 782.1

You’ll typically find the 782.1 inside:

• Tissot ladies’ dress watches from the 1960s and early 1970s

• Slim oval, round, or rectangular gold-plated cases

• Elegant bracelet-style watches with minimalist dials

• Some compact unisex models, often marketed as formal wristwear

These watches often featured two-hand time-only dials, acrylic crystals, and modest case sizes, reflecting the stylistic trends of the era.

Durability and Servicing

The Tissot 782.1 is valued for its low complexity and high serviceability. Spare parts may still be obtained through vintage parts networks or donor movements from the 780-series (such as 781, 782, 783, or 784).

Because of its robust and minimal design, the 782.1 continues to perform well when properly serviced every 4–6 years. It is especially ideal for collectors or wearers who prefer manual-winding simplicity in a vintage format.

Collectibility and Value

While not a high-end or rare caliber, the 782.1 has consistent appeal due to:

• Authentic Swiss mechanical construction

• Compact size suited for discreet or feminine wear

• Affordable vintage pricing

• Historical relevance in Tissot’s mid-century production

It offers great value to those seeking a dependable vintage mechanical watch with elegant proportions and a classic appearance.

Conclusion

The Tissot caliber 782.1 is a charming, compact manual movement that served as the engine for many of Tissot’s vintage dress watches. Built on the foundation of Swiss watchmaking efficiency and precision, it reflects the brand’s commitment to mechanical quality—even in its most modest-sized models. Today, the 782.1 remains a reliable, understated, and elegant choice for lovers of vintage wristwatches.
