30-day money-back guarantee — if Mazalgo doesn't save you time within 30 days, we'll refund every dollar.

Built for independent watch dealers, traders, and active collectors who buy and sell — even a few pieces a year. Not a marketplace, and not for retail boutiques or collectors who only buy and hold.

Worked example of a Mazalgo buy range for Rolex GMT-Master II 126710BLNR: 44 verified auction results from May 1 to July 9, 2026, low clear $14,800, median $18,500 sell target, auction anchor $14,110 at 15% below the auction midpoint
A worked example from verified auction records — not a screenshot. The workbench adds live eBay comps on top and shows every number behind the range.

What it does for you

  • See true margin after fees. Every B3AF (Bottom 3 After Fees) buy range shows the comps behind it — no black-box estimate. The formula is public on the methodology page.
  • Catch WTB buyers first. Want-to-buy posts from Reddit and WatchUSeek land in your workbench within 30 minutes and are matched against your inventory.
  • Verify before you wire. Deal safety checks and counterparty verification before money moves.
  • Turn a small bankroll faster, with a system behind you. Reuse capital sooner — clean margin math on the way in, a matched buyer on the way out.
  • Never quote a watch you already sold. One inventory of record — buyer matching only runs against pieces still marked Available.
  • Let OpenWatch draft the outreach. Two message variants per WTB match, queued for your approval — nothing sends without you. See how OpenWatch works.

Straight answers

Is the pricing a black box?
No. Every buy range shows its comp basis, and the B3AF formula is published at mazalgo.com/methodology. Auction data can lag; we say so.
Will the WTB feed keep working?
Leads come from public posts via Reddit's official API and public RSS feeds, refreshed every 30 minutes — no account scraping.
Can other users see my inventory or pricing?
No. Row-level security keeps your inventory, pricing, and contacts private to you.
How much work is it to move my inventory in?
One watch at a time, by hand — brand, model, reference, cost basis, condition, papers and box, photos. Contacts import from a CSV. There's no inventory CSV import yet, so if you're moving a large book, email support@mazalgo.com before you start.
Is there a learning curve?
Nothing to install — it runs in the browser. Price one reference in the Pricing Analyst, then add one watch; the deal pipeline and CRM work the way your spreadsheet does, with the fee math done for you. Docs live at docs.mazalgo.com, and the 14-day trial covers the full stack so you can judge it on your own inventory.
Does Mazalgo delist a watch everywhere when it sells?
No. Mazalgo doesn't push delistings to eBay, Chrono24, or your WhatsApp groups — pulling listings off other channels is still on you. What it does is keep one inventory of record: mark a piece sold once and buyer matching stops on it, because matches only run against watches still marked Available.
