Up for sale is my mint PROSPEX SPB143 Diver, Seikoās re-issue of their first professional diver model, the venerable 62MAS. If youāve seen it, you know it, and if you havenāt, itās worth checking out. Itās sleek and comfortable. The charcoal/bronze/grey sunburst dial changes colour with the lighting, and is framed by a black unidirectional rotating elapsed timing bezel along with a date calendar and LumiBrite hands and markers. Dress it up, dress it down, or undress and go diving, this watch can do it all.
Why am I selling this strap-monster? I follow the international 1-in 1-out rule. Were I to not abide by this, my home would be overrun with watches, as they reproduce like bunnies. This watch has been gently worn and has yet to see the wet stuff. The case is crisp and clean, the bracelet has a few desk-diver scratches that Iāve tried to capture in the photos. It as a full kit including all of its links (currently sized to ~6.3ā). Warranty card dated 7/26/22.
Additional specs include:
