I’m looking to Sell/ Trade my Tudor BB 41. Watch looks & runs very well. I’m including 6 extra Bands - $750+ Value! I bought the watch new almost 2yrs ago. Has been worn very little because I have a large collection, & I am a carpenter - not a very conducive environment to wear a watch that you’d like to keep nice. 1.) Phoenix Nato New & unused 2.) Tudor OEM Leather band & OEM Deployment Clasp 3.) Tudor OEM Black Nato - Only worn 5-6 times 4.) Custom Lizard band - Green w/ Red Stitching & a Deployment Clasp, New & unused 5.) Custom Lizard band - Brown w/ Cream Stitching & a Deployment Clasp, New & unused 6.) Green Tight Weave Nylon (sailcloth) w/ Leather & Deployment Clasp - Minimal Wear For trade: I’m open to hear what you have. Please, it has to make sense for me. I’m open to a lesser valued watch + cash, but I’m not looking to put out cash. Pre-Owned Trade Value $4150 For Cash Sale: $3699 What’s Included: Outer Box, Inner Box, Cards, Booklets, Hangtags, Purchase Receipt, & 6 extra Bands Any questions - Please feel free to PM me.
