The Tissot caliber 2031 is a manual-winding mechanical movement produced in the early 1950s, and it belongs to Tissot’s trusted 20xx series of compact calibers. Designed for small wristwatches, particularly ladies’ watches and slim unisex timepieces, the 2031 reflects Tissot’s emphasis on durable, efficient, and elegant mechanical design. Although mechanically simple, it was built to the high standards of Swiss watchmaking during the post-war boom.

Overview of the Tissot Caliber 2031

The 2031 was intended for time-only watches and typically features:

• Manual winding

• Central hour and minute hands

• A small seconds subdial at 6 o’clock (in most versions)

Watches powered by the 2031 were usually housed in round or square cases between 24 mm and 30 mm in diameter. These cases were made from stainless steel, gold-plated metal, or sometimes solid gold, and the overall design was clean and functional—suited for both daily use and formal wear.

Often seen in Tissot Antimagnetique or similar series, these models were aimed at wearers looking for precision in a compact and stylish format.

Maintenance and Service

To keep the movement in working order, the Tissot 2031 should be professionally serviced every 4 to 6 years. Dried lubricants and accumulated debris can cause excessive friction and wear, even if the watch still appears to run.

A full service includes:

1. Disassembly of all movement components

2. Ultrasonic cleaning of each part

3. Inspection and replacement of worn parts (such as mainspring or balance pivots)

4. Lubrication with modern synthetic oils

5. Reassembly and regulation

6. Case cleaning, and gasket replacement if present

Due to its straightforward layout, the 2031 is relatively easy to repair, especially for watchmakers familiar with vintage Tissot movements.

Common Wear Points

• Mainspring fatigue, leading to reduced power reserve

• Balance pivots and jewels may show wear from dry operation

• Small seconds pinion can wear over decades of continuous movement

• Stem and crown often wear down from regular winding

• Setting mechanism may become loose or misaligned with age

Despite its age, the 2031 is regarded as a durable and serviceable movement when maintained properly.

Handling Tips

• Wind the watch daily, stopping when you feel resistance

• Avoid moisture and water exposure, especially in older cases

• Keep away from strong magnets, which can affect timekeeping

• Store the watch face-up in a dry, padded box when not in use

Collectibility and Appeal

The Tissot 2031 is not rare, but it has a lasting place in vintage collecting for its:

• Mechanical simplicity and reliability

• Role in mid-century Tissot production

• Classic, understated designs in the watches it powered

• Accessibility for collectors new to vintage watches

It’s especially attractive to those seeking smaller vintage mechanical watches with real Swiss heritage.

Conclusion

The Tissot caliber 2031 is a compact, reliable hand-wound movement that powered many of the brand’s modest and refined wristwatches during the 1950s. With its solid construction, smooth operation, and straightforward servicing, it continues to perform well decades later. Properly maintained, the 2031 offers a charming and durable link to the golden era of Swiss watchmaking—perfect for both vintage enthusiasts and everyday wearers.
