Introduced in 1968, reference 3147N is a second generation Carrera with date featuring a subdial at the 3 o'clock position and a date window at 9 o'clock. It is not known how many were ordered by the Jordanian Air Force, however, to date, only 5 have been documented but it is thought that the production run was of 100 pieces. A unique and interesting feature for this Jordanian Carrera is the widely spaced one second markers on the crystal ring, probably added by request by the Jordanian air-forces to provide clearer legibility to its military personnel - the standard versions of the reference 3147N and all other period Carreras having more narrowly spaced 1/5th second markers.
The engraving on the caseback is in Arabic and literally translates as "weapon of height”. One notable scholar believes the characters stand for Silāḥ ul-Jawu al-Malakī ’al-Urdunī or the Royal Jordanian Air Force. The case back is also engraved with a military issue number which in this example is 80775.
It is rare to find a timepiece made for the Jordanian Air Force regardless of brand making the present lot an exceptionally interesting addition to the collector of military timepieces.
