What it is

A small online watch business selling everyday, vintage and pre-owned watches, plus basic extras like straps and batteries. You source stock, photograph it well, describe it honestly and post it out.

Your first three steps

  1. Learn the market: study sold listings on eBay and other marketplaces to see what everyday and pre-owned watches really sell for
  2. Buy a small first batch of watches from car boot sales, auctions or trade suppliers, and set up a marketplace seller account
  3. Photograph each watch well, list it with an honest description, and post it tracked and insured
Who pays

Individuals looking for a reasonably priced watch for daily wear, a gift or a collection.

How it makes money

You sell watches for more than you paid for them, and add small earnings from straps, batteries and gift packaging.
