Patek Philippe

quartz movement (cal.E26SC), 7 jewels, adjusted to one position, ribbed black dial, applied Arabic numerals, calibrated outer track with luminous hour markers, luminous hands, aperture for date, polished and satin finished case, screw-down case back, case, dial and movement signed, together with a stainless steel double folding clasp, accompanied by a presentation case and outer card box  

Interestingly the dial of this watch appears to have been inspired by the design of earlier military wristwatches and, in fact, the original Patek catalogue refers to the ribbed dial as 'Army Black'. Production of this reference commenced in 1998.
