FOR TRADE – 2025 Sinn U15 Limited Edition (1 of 1000)
Up for trade is my 2025 Sinn U15, a limited edition of only 1,000 pieces worldwide. This is a truly special watch and an absolute standout in the Sinn lineup.
The dark ink gloss dial is stunning in person, shifting through different shades depending on the light and angle—subtle, deep, and incredibly dynamic. Photos don’t fully capture how good it looks on the wrist.
At 41mm, the U15 wears perfectly on a wide range of wrists, striking an ideal balance between presence and comfort. The new adjustable clasp is a major upgrade from Sinn and makes dialing in the perfect fit effortless—one of the best clasps they’ve produced to date.
Trade Value: $4,500
If you’re looking for a modern Sinn with real character, rarity, and everyday wearability, this one checks all the boxes.
Don’t miss out on this special watch!
