サザビーズさんのインスタグラム写真 - (サザビーズInstagram)「From our new handle @SothebysWatches comes this beauty, a #Rolex Rare #YellowGold Anti Magnetic #Chronograph #Wristwatch with Pulsations Dial and Bracelet. Ref 4500, also known as the Monobloc, from circa 1946 is special for a number of reasons. First, it is one of very few Oyster chronograph models to feature only two subsidiary dials – for constant seconds and 30 minute register. Secondly, this gorgeous watch has a pulsations scale, used by medical professional to count the exact number of heart beats per minute. ❤️ Does it make your heart skip a beat?
