Personally I wouldn’t touch them with a barge pole, even if you paid me, not because of the quality of the watches but because of the Brand itself and how they have marketed their brand and the watches.
Well it’s hard to give an exact figure, I’m no expert or a retailer so just my opinion.
As Duke has said, these aren’t cheap or crap watches like Swan & Edgar, and definitely better than Solar Time/Resultco brands, but nor are they high end luxury watches as IW claim.
The one bit of credit I will give Duchamp, and this is probably as a result of the Brand Logic connection, is that unlike a lot of micro brands, like Swan & Edgar, Solar Time etc, they didn’t go the direct to China route when they started their brand, they went to a decent Swiss watchmaking Company, Watchmakers CH, who produce watches for a lot of different brands (Swiss, Non-Swiss, Fashion etc). Watchmakers CH are able to supply a range of watches from highly affordable (Sub £500) to entry level luxury (£500-£1500), they can do this by having facilities in Switzerland and Far East, so are able to supply from lower costs fully Chinese assembled watches (choices of various quality Chinese/Japanese/Swiss movements) to higher cost fully Swiss assembled watches (Choice of quality of Swiss movements).
I would say the nearest quality Chinese brands taking into account movements/finishing etc, would be the likes of San Martin, Sea-gull etc, definitely better than the average Ali Express or standard fashion brands.
Now to Duchamp, they have a few Swiss made watches, ie Audace £2995 rrp
, which is by far the best watch Duchamp sell, but it’s just another Rolex day/Date homage and copy of the Roamer Primeline which is produced in the same facilities. The Roamer retails around £700 (discounts and sales are available regularly) depending on bracelet or strap, but personally would be looking at paying a max of around £500.
At the other end of the scale you have the likes of the Grand Mont, has a £35 Swiss quartz in it, assembled in the Far East, Duchamp claim £1750 rrp
, similar quality and specs to the Roamer Rimini which can retail £200-£300, but the Rimini is assembled in Switzerland and Duchamp is assembled in the Far East so Duchamp is £150-£200 max, mostly due to the movement and decent case finishing.
So in summary, Duchamp would range from approx. £150-£500 depending on which watch in their range. They have 9 men’s watches and 5 Lady’s watches, only the men’s Audace comes near being worth £500, the rest would probably fit in the £150-£300 range.
Phew, need a cuppa coffee after that.
