Chrome-plated case of 38 mm, crown excluded, back fixed in injected polished cast iron stamped 'Basis Watch Swiss made de Luxe'. Push-buttons at 8 and 10 o'clock. Cream dial with multiple readings, number markers and gold hands, red central second hand and "Basis Sport - Swiss made" inscriptions. New polycarbonate glass. Original black strap, 19 cm excluding the pin buckle. Chronometer with a significant diameter (for the time), equipped with a Swiss mechanism: the upper push-button stops the second hand, the bottom push-button restarts it, no return to zero, the second hand stops by locking the balance.
