The design of the STR 4601 is inspired by high precision industrial tools and the dial design from vintage measuring instruments. It has the pat. pend. STR interchangeability functionality with the 90° turner. The steel used to produce the STR series is made out of recycled Swedish stainless steel to the the highest industrial quality standards.
DESIGN AND ENGINEERING
The Strayer watch was designed and engineered in Sweden in deep collaboration with the most skilled watchmakers and craftsmen in the heart of the high end watchmaking world, close to the Jura mountains, Switzerland. Spending a relentless amount of hours developing the initial idea for a proof of concept eventually lead to the design of the Strayer with the pat pend STR (System-Turn-Release) mechanism.
The idea behind the STR
How do you come up with something innovative in the watch world, one of the most competitive businesses out there?
By the beginning of the millennium Ola Stray, multi-award winning industrial designer and mechanical engineer, global head of design at one of the world’s largest industrial companies, was asking himself this very question. Ola wanted to design an elegant, mechanical wristwatch with interchangeability, to enable the wearer to express multiple designs with just one time piece.
The design concept
For the first series of Strayer watches the developed design enables the wearer to change the bezels with a simple 90° twist of the patented STR (Stay-Turn-Release) locking mechanism.
Finally, after more than ten years of development, the first Strayer watch was ready to launch with its pat pend interchangeble Turner-system. Allowing the wearer to express personality in a mechanical engineered way.
About Ola Strayer
In his daily work Ola leads in the design and innovation of high precision tools for both human and automated robotic usage. Working with clients globally including in the emerging electric vehicle market in California, high end sports car manufacturers in northern Italy and consumer electronics in Asia.
Spare time was spent developing and fine tuning the watch concept, taking it from a concept to a real product. Being a parallel iterative process consisting of ideation, design, drawings and evaluating prototypes together with the best watch manufacturers in Switzerland. The unique connection between Ola Stray and high end Swiss watch manufacture is evident from the use, in assembly, of two Red Dot Award winning tools designed by Ola in 2018 – thus setting the quality bar for the Strayer watch sky-high.
