What affects the price
Condition. Unworn and well-worn examples sell at different levels. Our ranges by condition, where a grade has enough sales:
- Unworn examples: $15,700–$21,200.
- Excellent condition: $13,600–$18,400.
- Good condition: $13,900–$18,800.
- Fair condition: not enough market data yet.
Card date. Because the 126603 is still made, buyers read the date on the card to judge how recently it was sold new.
Completeness. Box, papers, spare links and tags all help; missing papers are the gap buyers notice most.
Two-tone wear. Steel and gold wear differently. Look at the gold parts of a 126603 for thinning edges, since that is where heavy polishing shows first.
Dial. Expect buyers to compare the dial with the recorded one (black, gold 'Sea-Dweller' print) and to ask whether it has ever been replaced or restored.
Bezel. The 126603 has a unidirectional rotating yellow gold bezel with black Cerachrom insert bezel. Check that it turns cleanly and that the insert is undamaged and right for the reference.
Movement. It runs on the calibre 3235. A recent service with paperwork helps a sale; an overdue one is often priced into offers.
Retail. €21,300 (retail list price in France per 41watch and Monochrome Watches, January 2026).
Twelve-month change. Change over the past year: +6.0% over 12 months.
Tips for buyers
- Make sure the papers name reference 126603 and that the case measures 43 mm.
- Check the bracelet for stretch and the clasp for wear.
- Have an independent watchmaker inspect it within the return window.
- Look at the bezel (unidirectional rotating yellow gold bezel with black Cerachrom insert) for damage or replacement parts.
- Look at the card date to see how old the watch is.
- Ask whether the dial (black, gold 'Sea-Dweller' print) is original to the watch.
Tips for sellers
- Don't polish the case before selling.
- Collect the box, papers and any service records before you ask for offers.
- Shoot the watch in daylight from the front, both sides and the back.
- Use the published price data on this page as a starting point, and get more than one offer.
