In 2012 Patek Philippe introduced the 5123R-001, a contemporary timepiece in the Calatrava collection that still emitted the timelessness the collection is known for. The 5123R-001 has a round rose gold case, that is 38mm in diameter with an exhibition case back, a sapphire crystal and a smooth rose gold bezel. It comes with a silver-tone with rose gold index hour markers, small seconds hand and rose gold dauphine hands. The 5123R-001 is powered by the 215 PS caliber which is manually wound with a small second functionality and a power reserve of up to 44 hours. The case is paired with a stylish brown leather bracelet with a rose gold pin buckle closure. It has a water resistance of 30 meters (98 feet).
