Pilot BERKUT Flight Chronograph Poljot 31681

PILOT BERKUT Chronograph – Rare Watchmaking Heritage

The BERKUT Chronograph is a striking tribute to the legendary Russian fighter jet Sukhoi S-37 “Berkut” – the “Golden Eagle”. But what truly makes this watch stand out for enthusiasts and collectors lies within:

A rare and increasingly hard-to-find Poljot 31681 hand-wound movement – a genuine piece of Russian horological history.

The Heart: Poljot 31681 – Becoming Rare

The 31681 caliber is among the last classic mechanical chronograph movements produced in Russia. Since the closure of Poljot/MakTime production, these movements have become increasingly scarce – making them highly desirable today.

For collectors, this means: not mass production, but substance with real future potential.

The 31681 is based on the legendary Poljot 3133, itself rooted in Swiss watchmaking. In the 1970s, Poljot acquired a full production line from Valjoux (Switzerland), laying the foundation for one of the most robust mechanical chronograph movements ever built.

The result: Swiss engineering combined with Russian durability.

Technical Excellence – Built for Reliability

• Hand-wound movement with 25 jewels
• 21,600 vibrations per hour / 3 Hz
• Durable cam-switching chronograph mechanism
• Incabloc shock protection
• Power reserve: approx. 42–45 hours (chronograph off)
• Power reserve: approx. 37–39 hours (chronograph running)

Special feature of the 31681:
Unlike the 3133, this movement includes an additional 24-hour indicator – a practical complication especially appreciated in pilot watches.

Why This Movement Is Highly Collectible

• Production discontinued – getting more and more rare
• Historical connection to Swiss Valjoux technology
• Proven, robust construction
• Classic mechanical hand-wound chronograph
• Rising demand with limited availability

In short:
A mechanical movement with character, heritage, and true collector’s appeal.

Classic Pilot Design – Inspired by the “Berkut”

The clean black dial reflects the essence of aviation design. Large white minute numerals, luminous hands, and high contrast ensure excellent readability – just as expected from a true pilot watch.

A distinctive detail at 12 o’clock features the stylized front view of the Berkut jet.
