The Schaffhausen-based International Watch Company has a motto that will resonate with watch lovers - 'Probus Scafusia', or 'good, solid craftsmanship from Schaffhausen'. Sure it's not the most glamorous of phrases, but a robust build is critical to watchmakers and their clientele, and that's exactly what IWC promises and provides. Their entire collection exudes strength and durability, from the solid Ingenieur to the more stylised Da Vinci. While the company's heritage dates back to the 19th century, their current lines are the epitome of modernity. Rolex is a brand renowned for its heritage. It is also famous for its pioneering spirit. Over the past century Rolex has produced some of the world's finest and most luxurious watches, as well as some of the most groundbreaking wristwatch technologies of their time. The Oyster, released in 1926, and the Datejust, which came 20 years later in 1945, are two of the most famous breakthroughs. The former was the world's first waterproof wristwatch, while the latter was the first to automatically change date. In a nod to history, both watches can be bought today in their modern guises - icons updated.It's not all about the past though. As well as producing some of the world's most beautiful watches, Rolex continues to sponsor many of the world's most high profile events and expeditions. Its support of projects as varied as land speed records and deep sea exploration is indicative of a brand that strives to maintain its pioneering spirit and remain at the forefront of its craft.
