Schaffhausen/Singapore, 20th October 2022: Singaporean streetwear designer Mark Ong AKA Mr. Sabotage has created a limited-edition watch strap set for IWC Schaffhausen. The calfskin strap is available in two different widths and features the green camouflage pattern, which has become the visual trademark of the Singaporean’s sneaker customisation and streetwear label, “SBTG”. The IWC x SBTG special edition strap can be fitted on various IWC Pilot’s Watches, including the Big Pilot’s Watch 43, Pilot’s Watch Chronograph 41 and Pilot’s Watch Mark XVIII and XX. The strap sets will be available in limited quantities on as of 20th October 2022.

Mark Ong discovered his passion for customising and painting sneakers during his childhood as a skateboarder. His artistic and craftsmanship skills developed out of a necessity: he used leather, rubber, or even bicycle tires to patch holes in his shoes so he could carry on skating. When Ong couldn’t afford a pair of coloured sneakers one day, he bought a cheaper pair of white ones and started painting them himself. In 2002, he sold his first customised pair online and launched his sneaker customisation label, “SBTG” (short for Sabotage) the following year. Since then, the Singaporean has customised and hand-painted thousands of sneakers and collaborated with many leading brands in the industry. Among his loyal clients are athletes, rock stars, and fashion designers.

Now, Mark Ong and IWC Schaffhausen have teamed up for a unique collaboration based on their shared passion for craftsmanship and design and the attention to detail that both brands put into their work. The outcome is the IWC x SBTG special edition strap. Made of calfskin and available in two different widths, the straps feature the green camouflage pattern, which has become the signature aesthetic element of Ong’s work as a streetwear designer. Another detail paying tribute to the designer’s signature style is the embroidered patch featuring the strap specifications.

“I first became aware of the camouflage motif when I was skateboarding back in the 1990s. It was a defining moment for me, as it gave me inspiration to design streetwear by juxtaposing different elements. Over the years, camouflage-inspired patterns and colours have become synonymous with my work and brand, so it was clear from the onset that we would also incorporate these elements into the strap. We explored many different options and finally found something we were both happy with,” is how Mark Ong recalls the creative process.

The strap is an essential part of the watch and supports the attitude of the entire timepiece. We have done a couple of very exclusive and bespoke straps and the past, but our project with Mark takes it to a completely new level. Marks’ artistic expression and his way of combining military and streetwear elements perfectly fit our idea of a contemporary interpretation of our iconic Pilot’s Watches. We worked together on a fantastic watch strap design that combines Mark’s design signature style with a lot of passion for finish and detail.
