The square-form caliber 28-28 Q SQU was engineered specifically for the Cubitus case architecture, its 28.5×28.5mm footprint matching the geometry of the openworked dial above it, so that the horizontal laser-cut strips of the blue sunburst dial align visually with the exposed bridges and mainplate beneath. This structural dialogue between dial and movement is the design's defining achievement — the skeleton treatment is not decorative overlay but a genuine window into a movement engineered to be observed through the dial plane. The baguette-cut diamond at six o'clock and the rhodium-plated micro-rotor engraved with matching horizontal lines and a blue Calatrava cross confirm the depth of finishing investment.\u003c\/p\u003e\n\u003cp\u003eThe 45mm diagonal platinum case carries contrasting polished and satin surfaces, a screw-down crown, and a baguette-cut diamond at six o'clock. The sunburst blue openworked dial presents horizontally laser-cut strips revealing the square skeletonized movement, with white gold applied baton hour markers, white gold rounded baton hands, snailed subsidiary counters for day, date, month and 24-hour indication by hands, and a high-definition metallized laser-engraved moon phase. A navy blue composite fabric strap with cream stitching and platinum fold-over clasp completes the reference.\u003cbr\u003e\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003eThis piece was recently unveiled at Watches \u0026amp; Wonders 2026 — please register your interest for priority access as soon as we are able to secure it for you.\u003cbr\u003e\u003c\/p\u003e","brand":"Patek Philippe","offers":[{"title":"Default Title","offer_id":48005575835892,"sku":"P6515S","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0266\/7141\/5373\/files\/patek-philippe-cubitus-5840p-001-perpetual-calendar-moon-phases-platinum-blue-openworked-dial-2026-patek-philippe-1232569949.png?v=1776352151","url":"https:\/\/wristaficionado.com\/products\/patek-philippe-cubitus-5840p-001-perpetual-calendar-moon-phases-platinum-blue-openworked-dial-2026","provider":"Wrist Aficionado","version":"1.0","type":"link"}
