Offered for sale is a very rare and important Swiss Onger chronograph, all stainless steel with pump buttons and an oversize 38x47mm case. the watch is in remarkable aesthetic condition, particularly its black lacquered dial, original and never restored with beautiful ivory-tone tritium hour markers as well as rare "Broad Arrow" type hands, without the slightest line or mark. Inside this sturdy steel case, the fine Swiss Landeron caliber 248, in like-new condition, works perfectly, keeping time chronometrically and allowing the seconds hand to start, stop and reset correctly. Note, in the caliber and at 10 o'clock and 4 o'clock, the two original spring-loaded movement stops, which allow enough tension to keep the dial perfectly still while setting the time, further acting as a shock protector!
