Heuer - Silverstone - 110.313F NOS - Men - 1970-1979

The watch shown is an automatic Heuer Silverstone chronograph. It is an iconic vintage watch from the 1970s, known for its cushion-shaped square case and the brown fumé dial.
Main features
Brand: Heuer (before it became TAG Heuer).
Model: Silverstone, named after the famous Formula 1 circuit.
Reference: The original vintage version with a brown dial like the one in the image is often identified as Ref. 110.313F.
Movement: It contains the legendary automatic Chronomatic caliber (Caliber 11 or its successor Caliber 12), one of the first automatic chronograph movements in history. A distinctive feature of this movement is the winding crown positioned on the left side of the case.
Design: a polished and brushed stainless steel case with a domed sapphire crystal and a date at 6 o'clock. I note, considering the current state of preservation and the fact that it comes with official warranty, in my view I would define it as NOS (NEW OLD STOCK). The link between the Heuer Silverstone and the world of motor racing is deep and intentional, dating back to the 'golden era' of Formula 1 in the 1970s.
The Name: The watch takes its name from the legendary Silverstone Circuit in Northamptonshire, England, home of the British Grand Prix and synonymous with international motor racing. Choosing the name of a circuit, rather than that of a driver, has strengthened the brand's association with the very essence of competition and performance.
The Golden Era: Launched in 1974 as the successor to the Monaco, the watch's bold and angular design captured the spirit and the curved shapes of the circuit. At this time, Heuer was the official sponsor of Scuderia Ferrari, and its watches were very popular among the drivers.
The Iconic Pilot: The blue-dial model, in particular, is often nicknamed 'Clay Regazzoni' because it has been frequently spotted on the wrist of the famous Swiss racing driver.

The Iconic Pilot: The blue-dial model, in particular, is often nicknamed "Clay Regazzoni" because it was frequently seen on the wrist of the famous Swiss Formula 1 driver Clay Regazzoni, who raced for Ferrari in those years. Regazzoni even won a Grand Prix right at Silverstone in 1979.
The Caliber 12 is a historic and significant automatic chronograph movement, developed by a consortium of watchmaking companies in the 1960s.
Details of the movement
Joint Development: The movement is the result of a collaboration between Heuer-Leonidas, Buren-Hamilton and Breitling, who worked together to be the first to commercialize an automatic chronograph.
Architecture: It is based on a base movement (Buren 1280) with an added Dubois-Dépraz chronograph module. A distinctive feature is the winding crown on the left side of the case, while the chronograph pushers remain on the right.
Variants: The Caliber 12 was the improved and faster version of the first Caliber 11 (Chronomatic), which vibrated at 19,800 alternances per hour (A/h), compared to 21,600 A/h of the Caliber 12.
Innovation: At the time, this modular architecture represented a remarkable engineering feat, though the competition with Zenith (which developed the integrated El Primero) was fierce. The shipment is tracked and insured.
