Ladies and Gentleman, Greetings from the hills of Tennessee! ***I am offering you this rare piece, selling for my very close friend.*** This early rare Sinn “Excel-O-Graph” Navitimer features the rarely seen and often coveted Excelsior Park column wheel chronograph movement which really sets this piece apart from the pack. The blue dial with white subdials has developed an insane spider dial patina originating from the tritium (very similar to many Rolex blue dial watches of the same era). It's a beautifully unique patina that looks amazing with the rest of the dial colors. It looks awesome on the wrist and this watch has a ton of pop! The pictures say more than I ever could! Enjoy! Watch measures ~43mm with 22mm lugs. Please ask any questions you can think of and I guarantee whoever gets this piece will not be disappointed! **Asking Price: $3950** Negotiable, Depending on Trade, etc. Bring on your offers! Don't be shy :) *CONDITION DETAILS:* *Good condition stainless steel case. Original tritium lume on dial and hands. The minute hand does show some lume loss as seen in the photo. Watch is currently running strong with all functions working properly. The crown was replaced. Everything else appears to be original.* **All pictures are of the actual watch you will receive. Please study them carefully. Wrist is ~7inches for reference.** TIMESTAMP: [Timestamp](https://photos.google.com/share/AF1QipMD4nvG9ny806JCTxksL4WJV3K6-4YYQO4Xx8E8OJNtNtwpMAN5-Qk49XFTS-zHjA?key=eWRKUVlYX1JRRGtKRElxd0kzb2E3NkJ2c240UjBR) ALBUM: [Picture Album](https://photos.google.com/share/AF1QipPRGq5HuJpsVK36c9vrsp5BcT_K1JkMw78nVEm9LiL1z4T_pVLSMLZSFc6OY0oaww?key=TE92d09RS1gzQjNnc3dON3RjSFZmOXpXSllFeFdR) **Sale Price: $3950** OBO Including Shipping to USA (contact me for international shipping costs) **FINE PRINT:** *I am open to trades.
