Cartier Santos de Cartier Large (WSSA0018): BV Factory Accuracy Review & Buying Guide
Created in 1904 for aviation pioneer Alberto Santos-Dumont, the Santos is the world’s first modern men’s wristwatch. We review BV Factory’s 1:1 clone of the modern Large Model Ref. WSSA0018.
When Cartier revamped the Santos collection in 2018, they introduced a sleeker, curved bezel that extends seamlessly into the bracelet shoulders, coupled with two game-changing innovations: the QuickSwitch strap exchange mechanism and the SmartLink tool-free bracelet adjustment system.
In the 1:1 super clone sphere, BV Factory (BVF) is universally acknowledged as the supreme master of Cartier timepieces, capturing the aesthetic elegance and mechanical subtleties of the Maison with staggering precision.
1. Case Dimensions & Proportions (39.8mm × 9.38mm)
The Large model (Ref. WSSA0018) boasts commanding yet refined proportions. BV Factory nails the exact genuine measurements:
- Width: 39.8mm across the case.
- Lug-to-Lug: 47.5mm with curved ergonomic case architecture that hugs the wrist contours comfortably.
- Case Thickness: 9.38mm (genuine: 9.38mm). It slides effortlessly under a tailored French cuff.
- Crown: Seven-sided stainless steel crown set with a faceted synthetic blue spinel cabochon displaying correct deep indigo transparency.
2. Mechanical Ingenuity: QuickSwitch & SmartLink Systems
What sets BV Factory far apart from cheaper alternatives is the mechanical execution of Cartier’s proprietary bracelet technology:
- QuickSwitch Mechanism: By pressing a concealed push-button beneath the end-link, the bracelet releases instantaneously without tools, allowing you to swap between the stainless steel bracelet and leather strap in under five seconds.
- SmartLink Link Removal: Every individual link contains an internal spring-release button. Pressing the button with a fingernail pops the link pin out smoothly, enabling effortless sizing at your desk. BV Factory replicated this microscopic mechanical assembly with zero play.
3. Opaline Silver Dial & Secret Cartier Signature
The dial features an opaline silvered finish with black printed Roman numerals. Under a 10× loupe:
- The microscopic ‘CARTIER’ secret signature is cleanly integrated into the upward stroke of the VII Roman numeral (or X on some references).
- The blued-steel sword hands exhibit true thermal heat-treatment, reflecting brilliant royal blue highlights when light strikes the dial.
- The date aperture at 6 o’clock features crisp black numerals on a matching silver date wheel.
4. Calibre 1847 MC Clone Movement Performance
BV Factory equips the Santos Large with an ultra-reliable Japanese Miyota modified clone of the Cartier in-house Calibre 1847 MC. Running at 28,800 vibrations per hour, it delivers a 42-hour power reserve, robust anti-magnetic performance, and exceptional long-term reliability requiring virtually zero maintenance.
