( item code LePhare001)
Le Phare very rare professional underwater chronograph at 20 atm (200 meters – 600 feet) equipped with mechanical depth gauge in the calibrated glass up to a depth of 100 meters. Made in ’70 years.

External ring orange / yellow with indication of the immersion depth in meters. Pleasant colorful three-tone dial: black, orange and white. Extremely rare watch.
Depth Gauge Operation: at 3 o’clock the glass has a hole through which, during the immersion, the water enters, introducing itself inside the glass inner tube, which follows the circumference of the same. Going deep into the water finds greater resistance to entering, therefore advances inside the tube in an ever smaller way. The water that advances inside the tube is clearly visible externally from the glass, and the external graduated ring allows an easy reading of the depth reached.
Case: steel in three bodies screw-locked caseback and fixed outer ring in yellow / orange aluminum with graphic printed in black with indication of the depth meters reached during the dive.
