Vintage Patek Philippe Calatrava 1578J Spider Lugs

Condition: In immaculate condition and unworn since a full Patek Philippe service in 2014.  Case/Dial: Solid 18KT Yellow Gold case 35mm (plus crown) x 10mm deep x 41mm from lug tip to lug tip. The spider lugs accommodate a 20mm strap so overall this watch has more of a contemporary fit on the wrist than the dimensions might suggest. Silver coloured raised enamelled dial with raised lapped indices – very hard to find in this beautiful condition.  Movement: Patek Philippe Manual movement cal 27SC 18000vph (tested on our timegrapher and all good). Bracelet/Strap: Unworn Patek Philippe Matte Black Alligator Leather strap and PP 18KT Yellow gold buckle. Box/Papers: Patek Philippe Service Box and Archive papers (are on order but we think they will confirm a production date of around 1959). Reference numbers: Model number 1578J Other Information: Produced in relatively small numbers between 1949 and 1962. With rare Spider Lugs and a wonderfully preserved case with visible hallmark this is not your average vintage Calatrava. Excellent Investment opportunity.
