The Tissot caliber 38.2 is a manual-winding mechanical movement produced by Tissot in the mid-20th century, most notably during the 1940s and 1950s. It was designed to power elegant, time-only wristwatches, many of which were marketed as everyday or dress watches. As a movement from the earlier days of Tissot’s in-house development, the 38.2 reflects the brand’s focus on functional reliability, solid construction, and ease of servicing.

Overview of the Tissot Caliber 38.2

The caliber 38.2 is part of the Tissot 38-series, a line of hand-wound movements built for slim, uncomplicated watches with hour, minute, and often small seconds displays. These watches were typically housed in round stainless steel or gold-plated cases, with dial sizes ranging from 32 mm to 36 mm, matching the style trends of the era.

Tissot used this movement in both domestic and export models, offering a Swiss-made product that combined quality mechanics with timeless design.

Maintenance Guidelines

Being a vintage movement, the Tissot 38.2 requires routine servicing to ensure continued performance. Recommended service intervals are every 4 to 6 years.

A full service should include:

1. Complete disassembly and ultrasonic cleaning of components

2. Inspection of the mainspring, gear train, and balance assembly

3. Lubrication using modern synthetic oils

4. Timing and regulation in multiple positions

5. Replacement of worn parts, where available, or use of donor movements

6. Case cleaning and gasket replacement, though many watches of this era were not sealed

Common Points of Wear

• Worn mainsprings, which reduce the power reserve

• Balance pivots and jewels that may show wear from running dry

• Loose or corroded crown stems, especially if the watch was exposed to moisture

• Worn keyless works, which may cause rough or inconsistent winding

Because these watches are now several decades old, their components often require close inspection, and service should be handled by a watchmaker experienced with vintage mechanical movements.

Handling and Storage Tips

• Wind the watch daily, preferably at the same time each day, and stop when resistance is felt

• Avoid moisture and dust, especially since most vintage cases lack modern water resistance

• Keep away from strong magnets, which can affect accuracy

• Store face-up in a dry, stable environment to reduce wear when not in use

Collectibility and Legacy

The Tissot 38.2 is not widely known outside of vintage watch circles, but it is valued for its:

• Reliable performance

• Ease of service

• Classic mid-century Swiss design

• Historical significance in Tissot's production history

Watches using this movement are ideal for those interested in vintage Swiss mechanical watches without entering high-end collector pricing. They offer a tangible link to Tissot’s heritage and the post-war evolution of wristwatch design.

Conclusion

The Tissot caliber 38.2 is a dependable and well-crafted vintage hand-wound movement that powered many of the brand’s mid-20th-century timepieces. With proper care, including regular servicing and gentle handling, it continues to offer solid mechanical performance and vintage charm. Whether as an heirloom, collector’s piece, or everyday vintage watch, the 38.2 stands as a reminder of Tissot’s commitment to quality and practicality in watchmaking.
