The FHF 32 is a manual-winding mechanical movement developed by Fabrique d’Horlogerie de Fontainemelon (FHF), one of Switzerland’s most historic and influential ébauche (movement blank) manufacturers. This caliber represents an early generation of compact wristwatch movements, likely introduced in the first half of the 20th century, during the transitional period from pocket watches to wristwatches.

It was designed to meet the growing demand for smaller, practical mechanical calibers, particularly in men’s wristwatches and sturdy, military-style timepieces.

Technical Specifications

• Type: Manual winding

• Diameter: Approx. 10½ to 11 ligne (est. 23.3 mm to 24.9 mm)

• Height: ~4.5 mm (may vary slightly by variant)

• Jewels: Typically 15 (some versions with 17)

• Frequency: 18,000 vibrations per hour (vph)

• Power Reserve: ~40–44 hours

• Functions: Hours, minutes, small seconds at 6 o’clock

Design Features

The FHF 32 reflects the characteristics of early wristwatch movement construction:

• Large, robust bridges, similar to early pocket watch movements

• Small seconds subdial, a common feature in early wristwatches

• Traditional Swiss lever escapement

• Durable components built for reliability under daily wear

It was often used in steel-cased field watches, military timepieces, and early dress watches, particularly before central seconds became standard.

Applications in Watchmaking

The FHF 32 was commonly used in:

• Wristwatches from the 1930s through the 1950s

• Manual-wind military-style watches

• Simple, rugged men’s watches

• Entry-level Swiss brands and export pieces

• Some converted pocket watches transitioning into wristwatch form

Its practical layout and ease of production made it a favorite for brands focusing on function and reliability.

Watchmaker’s Perspective

Watchmakers view the FHF 32 as:

• Mechanically simple and accessible

• Durable, with many examples still running today

• Easy to clean and service, though early versions may lack shock protection

• A solid candidate for vintage restoration and beginner horology practice

Conclusion

The FHF 32 is a straightforward, robust manual movement from the early days of wristwatch development. It exemplifies FHF’s commitment to making dependable calibers that powered millions of watches during a pivotal period in horological history. With its traditional architecture and long-term reliability, the FHF 32 remains a valued caliber in vintage collections and restoration workshops.
