BIG TURTLE
Big Turtle Small Second
“Majetek” refers to the cushion-case pilot’s watches commissioned by the Czechoslovak military from Longines, Eterna and Lemania between 1935 and 1945. The early Longines version, often called the “Big Turtle,” is admired for combining a rugged presence with decorative detail. We have faithfully recreated its balanced design in a practical watch.

HISTORY & DESIGN
The history and details behind this watch.
“Majetek” refers to the cushion-case pilot’s watches commissioned by the Czechoslovak military from Longines, Eterna and Lemania between 1935 and 1945. The early Longines version, often called the “Big Turtle,” is admired for combining a rugged presence with decorative detail. We have faithfully recreated its balanced design in a practical watch.
The triangular pointer moves with the rotating bezel and can be positioned to measure elapsed time.
A distinctive pilot’s-watch design
The decorative coin-edge rotating bezel and cobra hands might seem at odds with the substantial cushion case. The distinctive Y-shaped lugs bring these elements into balance. We also recreated the original case-back construction, fastening the upper and lower parts of the case with screws.
The crossed swords at the upper right of the case signify military ownership. Our original account also relates them to the bravery of Czechoslovak pilots who joined the Royal Air Force after their homeland was occupied by German forces and fought to win it back.
Big Turtle Small Second
As on the original, the small-seconds display is balanced at 6 o’clock and is easy to read. The maker’s “Montre roroi” signature appears in script at 12, with “ANTI-MAGNETIQUE” above the small-seconds display. An internal antimagnetic plate provides magnetic resistance.
