Glad you decided on the 5088P. Of all the current and recent champleve enamelled references from Patek, including the 50th anniversary Golden Ellipse but short of the new Sky Moon Tourbillion in rose gold and brown champleve enamel, I think the 5088P Calatrava is the most exquisitely made ... its the only one where the case and pin buckle are also champleve enamelled. The Arabesque and Volutes decor pattern on the 5088P I also find to be the most attractive and difficult to render.
