Monocoque

Monocoque Cases: A Hallmark of AGAT A watch case usually consists of several elements: a caseband, bezel, caseback, crystal and crown. Each connection must be precisely fitted, and every joint is a potential point of vulnerability. AGAT watches are constructed differently. They have no separate caseback: the case is machined from a single piece of metal. This one-piece construction is known as a monocoque case.

The movement is fitted into the monocoque case from the dial side. The watch is subsequently serviced from the dial side as well. This configuration may seem unconventional, but the logic is simple: fewer openings and joints mean fewer potential paths for water ingress. The one-piece metal case enables AGAT watches to dive to depths of up to 750 metres while maintaining precise timekeeping.

For the Zlatoust Watch Factory, the monocoque is more than just an engineering solution. This is the calling card of AGAT watches.

The Zlatoust monocoque dates back to the mid-20th century, when the factory received a special order from the Soviet Navy. Its engineers had to create a watch able to operate reliably underwater, withstand high pressure at depth and retain its accuracy.

The solution was to minimise openings, joints and potential paths for water ingress. The movement was housed in a monocoque case machined from a single piece of steel — a design later known as a unibody.

This design remains a defining feature of AGAT watches. Whether made of steel, bronze, titanium, zirconium, titanium Damascus or titanium-zirconium Damascus, the cases are solid, all-metal monocoques. Today, ZChZ remains the only manufacturer in Russia to produce wristwatches with monocoque cases.

In a world where many watches look alike, AGAT has retained its own architecture. It is neither borrowed nor decorative: its form grew from a practical requirement, not from fashion. That is why it feels so convincing.

A monocoque case has a distinctive beauty: not ornamental, ostentatious or delicate, but the beauty of metal and engineering — of an object made with a clear purpose.

AGAT watches are no longer restricted to specialist use. They are chosen by collectors, enthusiasts of Russian watchmaking and anyone who appreciates the aesthetics of large instrument cases. Yet the monocoque remains the core that connects the modern collection with the factory’s history.

It makes an AGAT watch instantly recognisable.
It preserves the logic of a diving instrument.
It gives the case the reassuring solidity of a single piece of metal.
It makes the watch’s massiveness a consequence of its construction, not a styling device.

Without the monocoque, an AGAT watch could still be large, strong and expressive. With it, the watch becomes unmistakably itself.

It is not a detail visible only to an engineer. It creates the first impression, inspires respect for the product and builds trust in the factory.

A monocoque is not merely a way of making a case.
It is a way of preserving character.
