*Unpolished* 1950s Patek Philippe Calatrava 18K WG (Ref. 570) 'Cal. 27 SC'

While there are nearly countless options and iterations of Patek's classic dress watch line, the early references have captured the hearts of enthusiasts and collectors alike, with the ref. 570 being one of the most coveted and celebrated models in the iconic lineage. Introduced in 1938, the Calatrava ref. 570 was the second Calatrava created by Patek Phillipe, and in many ways a continuation of the original Calatrava design but with the increased case proportions of just over 35mm. Of the 2000 estimated examples produced, there were five metals used for the reference 570, including steel, 18K white, yellow, and rose gold, and platinum – with numerous variations of dial configurations featuring both center seconds and subsidiary seconds options.

The example presented here employs the Cal. 27 SC movement, which is manual winding with center seconds and is cast of 18K white gold with a classic dial, achieving the Calatrava aesthetic in its purest form.

CASE & BRACELET

The incredibly well-preserved and crisp 18K white gold case is believed to remain unpolished with all of the original factory finishing present, exhibiting no evidence of being previously polished with sharp lug holes and honest signs of light use present throughout. The case retains its original crown adorned with the Patek Philippe cross, which features a warm patina. The case back retains its original factory dimensions and crisp finishing throughout, with gentle signs of previous use present. The watch comes supplied on a 2pc handmade lizard leather strap.

DIAL & HANDS

The original and brilliant satin silver dial features a classic aesthetic with a drilled minute track and bullit-style hour markers. The dial itself is exceptionally well-preserved for its age, with only one small notable mark present to the right of the hand stack and some nominal aging at the very edges of the dial that is invisible to the naked eye. The original dauphine hands with center seconds are also in remarkable condition, showing nominal oxidation in the seconds hand.

ACCESSORIES

None. The watch is keeping time, though the service history is unknown. A movement service can be purchased upon request.
