The Cartier Santos WGSA0007 is the Santos with nothing held back — the large model rendered entirely in 18K pink gold. Case, bezel, screws, crown, bracelet: all of it warm rose gold, wrapped around a silvered opaline dial with radial Roman numerals and blued sword hands, with a faceted sapphire set into the seven-sided crown. It runs the automatic 1847 MC, resists water to 100 meters, and — tellingly — Cartier ships it with two attachments on the QuickSwitch system: the solid gold SmartLink bracelet and an alligator strap.
That second strap is Cartier admitting what every owner of a gold watch knows: a solid gold bracelet is glorious and slightly terrifying to wear every day. The strap is how this watch actually lives. This guide covers the correct size and the most popular Helvetus options for the WGSA0007.
Cartier Santos WGSA0007 Strap Size and Fit
For the Cartier Santos WGSA0007:
- Model: Santos de Cartier, large model, 18K pink gold
- Case width: 39.8 mm
- Case shape: square
- Strap system: Cartier QuickSwitch (tool-free interchangeability)
This means the watch requires a 21mm (Large) strap made for the Santos quick-release system. When ordering, simply select the 21mm (Large) option on the product page.
As with every modern Santos, a regular 21mm strap will not fit — the case has no traditional lugs, so only QuickSwitch-compatible straps click in securely and sit flush against the case. Every Helvetus Santos strap is built exactly for this.
Gold Is for Wearing — Carefully
Pink gold is soft. The bracelet's polished links pick up hairlines from a desk edge, and on a full-gold reference, bracelet condition is the single biggest factor in what the watch is worth later. Which is why so many WGSA0007 owners run the same playbook: the gold bracelet lives in the box for the moments that deserve it, and the watch lives on straps the rest of the time.
The reward goes beyond preservation. A pink gold Santos on a strap is one of the great modern looks — the case glows against leather or rubber, the watch drops weight, and the whole presence shifts from formal to effortless in one click.

Below are the most popular choices among owners of this reference, matched to its pink gold case and silvered dial.
Brown Leather Strap
Pink gold and brown leather is a pairing as old as fine watchmaking, and it is the natural successor to the alligator strap in the box. Warm on warm, rich and classic — this is the strap that makes the WGSA0007 look complete. Brown Leather Strap for Cartier Santos Quick Release
Black Rubber Strap
Gold on rubber is the modern statement, and few watches carry it like a pink gold Santos. Black rubber makes the case the only warmth on the wrist, adds waterproof practicality, and turns a formal watch into an everyday one — without losing a gram of presence.

Blue Leather Strap
Look closely and the blue is already there: in the blued sword hands and the faceted sapphire crowning the winder. Blue leather draws that thread across the wrist, and the cool-against-warm contrast with pink gold is quietly spectacular. Blue Leather Strap for Cartier Santos Quick Release
Navy Blue Rubber Strap with Screws
For owners who want the design language everywhere, this strap mirrors the bezel's exposed screws on the strap itself — in a deep navy that flatters pink gold beautifully. Sporty, distinctive, and unmistakably Santos. Navy Blue Rubber Strap with Screws for Cartier Santos
