About the collection
Simple, legible, housed in a durable and lightweight titanium case. Colour-coordinated to emphasise the sporty appearance. The orange second hand harmonises with the resilient rubber strap. For the first time in the history of the PRIM Automatic line, the dial inscription is split into two colours.
The highlight of the solid caseback is the two-blade winged propeller, a tribute to the origins of Czechoslovak civil aviation – this symbol once adorned the buttons of pre-war ČSA crew uniforms. Water resistance has been increased to 10 ATM, making the PRIM OK-A suitable for wear even in demanding conditions.
The watch is delivered on a rubber strap.
Inside the watch beats Caliber 71 with automatic winding (SELLITA SW200-1).
This limited edition comprises just 50 pieces.
About the model
Simply superb pilot watches.
Legibility, durability and clarity. That is what pilot watches are all about, first and foremost. Contrasting colours and a consistently refined look, even for everyday wear.
The dial is dominated by bold numerals and the signature triangle marker at 12 o’clock. Hands with large luminescent surfaces and a prominent second hand ensure outstanding readability even in poor conditions.
When designing the model, the goals were clear – and all were achieved:
- Create pilot watches with an automatic movement
- Modernise the design of previous pilot models
- Develop an attractive colour combination
- Respect the fundamental hallmarks of aviation watches
- Combine contemporary customer expectations with the original style
- Confirm durability and versatility
