A quiet market
for things worth a lifetime.
Sotto is an anonymous marketplace for pre-owned premium horology. KYC at the gate, escrow at the spine, audit at the seam. Buyers and sellers stay anonymous. The watch is the only signal.
Discretion
You are never the headline. Reputation travels without a face. Identity is verified once, to us — never to each other.
Trust
Every transaction sits on the spine of escrow. Funds are held by Sotto until the watch is in your hands and authenticated.
Permanence
We trade in objects that outlive their owners. Provenance, papers, service history — documented for every listing.
Four steps, on either side.
The process is identical for buyer and seller — same gates, same escrow, same paperwork. The trade closes in days, not weeks.
Verify once
Sumsub-backed KYC. Two minutes. You are now anonymous-to-each-other, verified-to-us.
List or browse
Sellers publish in six steps. Buyers filter by reference, era, condition, paperwork.
Match in chat
Anonymous 1-1 thread tied to the listing. Negotiate, ask for video calls, request additional photos.
Escrow & hand-over
Funds clear into Sotto. The watch goes to our authentication vault. On match, both sides settle.
Covered quietly,
by the people who notice.
“Sotto is the first marketplace that has internalised the obvious: the buyer of a € 90,000 watch does not want a profile picture.”
