Up for sale is a beautiful Audemars Piguet housing the legendary K2121. The K2121 is the movement that powered generations of Royal Oak models, or you may say that the K2121 is what built the Royal Oak. Other than that, this watch has the same marker design that appeared on the first Royal Oak. This watch was made in 1971 based on the serial of the movement.
• Case size: 34mm with 41mm from lug to lug.
• Housing K2121 caliber, which is based on the JLC 920, was also used by Vacheron Constantin. The movement was serviced and running well under +-10s/day. You may hear a slight rotor noise when using it, which is perfectly normal for this caliber. No quickset date, but you could use 10-12 method.
• Original 18kt white gold case, which was slightly polished with some slight signs of usage. There is a deep scratch at 5 o'clock on the bezel, but the watch still looks good overall.
• Original plexiglass crystal in good condition (polished).
• Original dial with some signs of degrading at 8 o'clock area but hard to notice under normal light condition, only visible under some angles.
