What the differences cost you
Each note below follows from the published figures in the tables above — what they mean for intake, for a listing, and for the handover. Nothing here estimates a price or a margin.
Where a shared listing template goes wrong
These two differ on case, diameter, thickness, lug width, dial and bracelet, among others. None of it changes how either watch is handled, but all of it changes what the listing has to say. Copy from one to the other and those are the fields that end up describing the wrong watch.
What to check on each
AB0145211G1P2
- Read the chronograph registers before you write the listing. Breitling lists this one as quarter seconds and 30 minutes, without the 12-hour totaliser its stablemates carry, so describing it as a 12-hour chronograph is simply wrong.
- Note the jewel count on the sheet. The same calibre name is published with 47 jewels elsewhere in the range and 41 here, and quoting the wrong figure is an avoidable error in a description.
- Check the strap is the curved type this reference specifies. A straight strap forced into a curved lug opening sits badly and marks the case where it is pinched.
AB01761A1K1X1
- Establish what came in the box and photograph all of it. On a themed edition the presentation packaging is part of what a buyer is paying for, and an incomplete set is worth materially less than a complete one.
- Check the published jewel count of 40 against whatever the seller has written. Breitling lists this calibre with three different jewel counts across the references documented here, so a mismatch means somebody copied a spec sheet from another watch.
- Confirm there is no date aperture. Unlike the other Breitling chronographs here, this reference has no calendar line on its page, and an inspector working from a general spec sheet may query a correct watch.
