Swatch x Blancpain Fifty Fathoms Antarctic Ocean SO35S100 SISTEM51 Bioceramic Watch. Worn twice outside. Like new. Full inclusion with receipt and warranty card from original purchaser. Extremely hard to find in store and these command a premium markup as a collectors item. A bit small for my liking so my loss is your gain. Listing price is below my purchase price on the resale market 💯 authentic
