JD1 Jaquet Droz Equation Of Time. Reference J009634201. Watch measures 43mm and is made from white gold. Automatic Jaquet Droz Manufacture in-house movement caliber 3666-4 which provides for 72 hours of power reserve. Sapphire crystals on both sides of the case. Slate grey stone dial with white gold applied index for the equation indication. Steel blued hands and please notice the sun on the equation hand is made with 2 colours of gold, a really beautiful and discrete touch. Waterproof 3ATM or 30 meters. Functions are hours, minutes, date, month and equation of time. This watch is fitted with a brand new black crocodile leather strap with white gold pin buckle. This watch comes from my personal collection (I used to work for JD) and it is with pain in my heart that I now sell it. I had the watch serviced in 2011 and the watch is still in an unpolished condition and is working fine. Please be aware that this watch was made in a limited edition of 28 pieces in white gold only as there were only 28 movements EVER made. Has lived in my safe ever since. This is by far the most pure EOT you can buy with the ONLY correct EOT indication of -16 to +14 minutes. Other high end brands offer this complication usually in combination with a Perpetual Calendar with an EOT indication of -15 to +15 minutes which is NOT correct in my view... 
Please be aware that this watch comes with the service paper only but I will add an extra brand new black crocodile leather strap and white gold buckle (also new). JD straps are around €700 retail. White gold buckle will be over €1000. A possibility to own a truly great understated watch that is extremely rare.
