In this Article Bonhams Hong Kong will be offering up one of the rarest minute repeaters produced by Patek Philippe in modern times at its watch sale later this month. The Patek Philippe Ref. 5033P dropped in 2002 and was the first watch to combine minute repeater with annual calendar, a complication Patek invented in 1996. The model, which was cased exclusively in platinum, except for a single titanium example [which sold last year for $1.9m USD], was updated in 2004 to replace its original Roman numeral hour markers with drop hour markers. Most of the total production run, thought to number around 80 pieces, used a white or “silvered” dial.
