Released in 2006, Patek Philippe reference 5396R-001 continues the legacy of the annual calendar complication from the storied manufacturer. The timepiece features a two-line annual calendar with moon phases and a 24-hour indicator. Distinguishing the present lot is a highly attractive and desirable sector dial, which draws inspiration from 1930s watches. The sector rings along with the thermally blued steel hands create a lovely contrast against the silvered opaline dial. These elements are vibrant and youthful yet provide an element of nostalgia to the complicated timepiece. Reference 5396 is housed in an 18k rose gold case and features a sapphire case back, further bringing the vintage-inspired watch into modernity.
