With a refined architecture comprising around 250 components and a high jewel count, this calibre reflects IWC’s commitment to technical excellence and durability.

The IWC Schaffhausen Portugieser Automatic is a true expression of refined Swiss watchmaking. Defined by its clean and balanced dial, it features elegant Arabic numerals, slim feuille hands, and a layout inspired by traditional marine chronometers. The 7-day power reserve display adds both function and character, reinforcing its reputation as a timeless and sophisticated timepiece.

This model is powered, in most cases, by the IWC calibre 79320, which is based on the renowned Valjoux 7750 (ETA).

IWC Pilot’s Chronographs produced between:

The calibre 79320 was widely used by IWC Schaffhausen until it was gradually replaced by in-house movements (such as the 69385) around 2016

The legendary Rolex Day-Date, introduced in 1956, was the first wristwatch to display both the day of the week in full and the date — a milestone that quickly made it a symbol of prestige and power, even earning the nickname “Presidential”.

Decades later, Rolex elevated this icon further with the Rolex Caliber 3035, introduced in the late 1970s. This automatic movement brought significant advancements, including a higher frequency (28,800 vibrations per hour) and a quickset date function, ensuring greater precision and everyday convenience.

The combination of heritage, innovation, and exceptional craftsmanship makes the Day-Date far more than a watch — it is a piece of history on the wrist.❤️❤️

🏁 A legend born for the track

The Rolex Cosmograph Daytona was introduced in 1963 by Rolex, designed specifically for racing drivers and motorsport enthusiasts. Its name pays tribute to the legendary Daytona International Speedway, one of the most iconic racing circuits in the world.

Over time, the Daytona evolved from a professional tool into one of the most coveted watches ever made — especially after its association with Paul Newman, whose distinctive dial variant became a true collector’s icon.

The heart: Rolex calibre 4030

In 2000, Rolex unveiled the in-house calibre 4130 — a major milestone in the Daytona’s history. Fully developed and manufactured by Rolex, it replaced outsourced movements and introduced several key improvements:

• Simplified architecture (fewer components, greater efficiency)
• Enhanced reliability and easier servicing
• Vertical clutch for smooth chronograph engagement
• Column wheel for precise start/stop/reset functions
• Approximately 72-hour power reserve

The calibre 4030 also features the Parachrom hairspring, offering greater resistance to shocks and temperature variations — ensuring exceptional accuracy in demanding conditions.
