Blancpain 6605-3642-55A Description

Condition and set

Any wear is visible in the photos, and we describe it as plainly as we can. Like new & unworn is the grade we assign after inspecting the case, dial, bezel, crystal, and bracelet, and the photos show the wear behind that grade. The set is described as "Original box, original papers". Box and papers document provenance, and a watch with a full set is usually easier to resell.

The reference number 6605-3642-55A separates this version from other variants of the model, down to dial, bezel and bracelet details, so match it against the photos before you buy.

This was my first purchase through Chrono24. Everything went perfectly. Communication with the seller was smooth, we reached a deal quickly, and everything was handled neatly and correctly. The watch is genuinely like new and meets my expectations 100%. With service like this, the added value of a local dealer is difficult to see. Shipping was also handled with the utmost care. Thank you!
