Before you buy a used Seamaster Diver 300M 210.30.42.20.01.001
- Prefer the Authenticity Guarantee. On eBay UK most watches over £1,500 are checked by an independent authenticator before they're sent to you. Look for the green tag on the listings above, or tick "Authenticity Guarantee" in the filters.
- Check the reference and serial. Ask for a photo of the reference and serial on the case back, and make sure they match the papers. The reference should be 210.30.42.20.01.001.
- Box and papers should match the watch. The serial on the warranty card must match the case. A "full set" with a generic box or papers from another watch is worth no more than the watch alone.
- Be wary of a price far below typical. Most fakes and scams are priced 30–50% under the going rate to look like a bargain. We flag anything 35%+ under similar listings and never count it as a deal.
- Ask about servicing. A full service costs £300–£900 at the brand, so a recent service with paperwork adds real value. Ask when it was last serviced and whether it keeps time.
- Look for polishing and replaced parts. Sharp case edges and unpolished lugs add value; aftermarket dials, bezels or diamonds take it away. We remove listings that say "custom" or "aftermarket", but check the photos.
- Pay through eBay. eBay's Money Back Guarantee only covers you if you pay through eBay. Never pay by bank transfer outside it, however good the deal. Our fake watch checklist has more.
Questions
How much is a used Seamaster Diver 300M 210.30.42.20.01.001 worth?
Based on today's eBay UK Buy It Now listings, a pre-owned Omega Seamaster Diver 300M 210.30.42.20.01.001 typically costs £3,995 as a full set with box and papers, including postage. Unworn examples are typically £4,003. These are asking prices, so a watch can sell for less, especially with Best Offer.
What is the retail price (RRP) of the Seamaster Diver 300M 210.30.42.20.01.001?
The approximate UK list price is £5,600 (brands change prices every year, so check with an authorised dealer). Pre-owned examples are listed at about 29% below that on eBay UK today.
What are the specs of the Seamaster Diver 300M 210.30.42.20.01.001?
The current 42mm Seamaster Diver 300M with a ceramic bezel, wave dial and 8800 Master Chronometer movement. Case size 42mm, steel, automatic movement, made 2018–present.
Is it safe to buy a Seamaster Diver 300M 210.30.42.20.01.001 on eBay?
It can be. On eBay UK most watches over £1,500 qualify for the Authenticity Guarantee, where an independent authenticator checks the watch before it reaches you. We tag those listings, flag sellers with little or poor feedback, and warn about prices far below typical, which is where most fakes and scams sit.
