Buying tips
- 01Cartier watches are dress watches — leather straps suit them far better than rubber or NATO.
- 02The Santos Large (42mm) uses 20mm; the Santos Medium uses 18mm.
- 03The Tank Louis uses 18mm and looks best with a slim, un-padded leather strap that tapers to 14–16mm.
- 04Alligator-embossed leather on other sites looks nearly identical to genuine Cartier leather at 5% of the price.

What lug width does the Cartier Santos use?
The Santos de Cartier Large (42mm) uses 20mm. The Santos Medium (35mm) uses 18mm. The Santos Small (27mm) uses 14mm.
What strap looks best on a Cartier Tank?
The Tank is a classic dress watch — it demands leather. A smooth or alligator-embossed leather strap in black or tan with a deployment clasp is the most authentic look. Search 'alligator embossed leather strap 18mm' on other sites for $8–$15 options.
Can I put a cheap strap on my Cartier without looking wrong?
Yes, if you pick the right style. Cartier's aesthetic is refined — a quality leather or milanese strap from other sites (with a deployment clasp, not a pin buckle) maintains that look at a tiny fraction of the official strap price.
