The Tissot caliber 2461 is a manual-winding mechanical movement from the 1950s to 1960s, produced during Tissot’s golden era of in-house mechanical watchmaking. Like other calibers in the 24xx family, the 2461 was built to power time-only wristwatches, focusing on accuracy, durability, and a slim profile. It was typically used in men’s dress watches and occasionally in mid-sized unisex models, reflecting the brand’s strong commitment to everyday functionality and understated elegance.

Overview of the Caliber 2461

The Tissot 2461 is a simple, hand-wound movement, known for powering watches with:

• Central hour and minute hands

• A small seconds subdial at 6 o’clock

These watches were often part of Tissot’s Antimagnetique, Seastar, or Visodate lines and were housed in round or cushion-shaped cases measuring 32–36 mm, often made from stainless steel or gold-plated brass. Dials were clean and minimalistic, in keeping with the aesthetic of the time.

Technical Specifications

• Type: Manual winding

• Functions: Hours, minutes, small seconds

• Jewels: 15

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

• Power Reserve: Around 40 hours

• Diameter: Approximately 27 mm (12 lignes)

• Height: Around 4 mm

• Shock Protection: Present in many examples (often Incabloc)

• Finish: Typical mid-century Swiss industrial finish with matte or brushed bridges and blued screws

The movement is constructed with a Swiss lever escapement and features a simple, reliable gear train layout suited for long-term use and easy serviceability.

Maintenance and Servicing

As with all vintage mechanical movements, the Tissot 2461 benefits from regular servicing, ideally every 4 to 6 years. Even if the watch runs well, old oils and accumulated dirt can cause wear over time.

A professional service includes:

1. Full disassembly of the movement

2. Ultrasonic cleaning of all parts

3. Inspection of key components such as the mainspring, pivots, jewels, and escape wheel

4. Replacement of worn parts using either original stock or donor movements

5. Lubrication with modern synthetic oils

6. Reassembly and regulation in multiple positions

7. Optional case cleaning and gasket replacement

Parts may not be in current production, but the 2461 is mechanically straightforward, and experienced watchmakers can usually source replacements or fabricate missing components when necessary.

Common Wear Areas

• Mainspring fatigue can lead to reduced power reserve and poor amplitude

• Balance pivots and jewels may show wear if the movement ran dry

• Small seconds wheel is under constant stress and can become loose or worn

• Stem and crown components may wear from decades of winding

• Setting components (keyless works) can wear or misalign

Despite these typical aging issues, the 2461 is considered mechanically stable and long-lasting when maintained properly.

Usage Tips

• Wind the watch daily, but avoid over-winding

• Store in a dry environment, away from temperature extremes

• Avoid water and moisture exposure, as vintage cases often lack modern sealing

• Keep away from magnets, which can disturb the balance spring and escapement

Collectibility and Value

The Tissot 2461 is not a rare collector’s item, but it is admired for:

• Authentic mid-century Swiss construction

• Simple and elegant mechanical design

• Affordable entry into vintage watch collecting

• Its place in Tissot’s rich mechanical history

It appeals to collectors seeking reliable vintage watches with mechanical integrity, as well as those who appreciate Tissot’s role in shaping 20th-century horology.

Conclusion

The Tissot caliber 2461 is a straightforward, durable manual-wind movement that powered many of the brand’s classic timepieces during the 1950s and 1960s. With its solid build quality, smooth winding, and elegant simplicity, the 2461 remains a great choice for anyone interested in vintage Swiss watches that combine mechanical performance with understated charm. When properly cared for, it will continue to offer reliable timekeeping and timeless appeal for decades to come.
