Think of Straps as Clothing for Your Watch
Just like how the right outfit changes how you feel, the right strap transforms how your watch looks and wears. Change the strap, change the watch — match your mood, your outfit, your occasion.
Dress It Up
A leather strap instantly elevates your watch for the office, a dinner, or a formal event. Rich patina develops over time, making it uniquely yours. It's the equivalent of putting a suit on your watch.
Go Active
Swap to rubber for the gym, the beach, or a dive. Waterproof, sweat-resistant, and easy to clean. Your watch goes from boardroom to beach bar in thirty seconds — without the metal bracelet catching arm hair.
Keep It Casual
A fabric strap is the watch equivalent of wearing jeans and a t-shirt. Lightweight, breathable, and effortless. Perfect for travel, weekends, and days when you just want your watch to disappear on your wrist.
Material Guide
Which Strap Material is Right for You?
Each material has a distinct character. Here's how to match your strap to your lifestyle.
Premium leathers like Shell Cordovan, Epsom, Baranil, and Alligator develop a rich patina over time. Ideal for office wear, dinners, and formal occasions. Available in slim and signature profiles.
FKM rubber and Sailcloth straps are fully waterproof, sweat-resistant, and easy to clean. Available in regular, waffle, tropical, and mosaic patterns. Cut to size for a perfect fit on your wrist.
Elastic Loop, Delcro, and Hook Straps are lightweight, breathable, and built for daily wear. Quick to put on and take off — great for travel, weekends, and casual use.
Installation Guide
How to Change the Strap on Your IWC Portofino Hand-Wound Big Date "Bucherer 125 Years"
Swapping a strap takes about 30 seconds. All Delugs straps come with quick-release spring bars — no tools needed to install.
A spring bar tool has a forked tip that releases the spring bars holding your current strap. Delugs sells one — or use any standard tool.
Insert the forked tip between the strap and lug. Press inward to compress the spring bar, then slide the strap out. Repeat for both bars.
Every Delugs strap comes with quick-release spring bars pre-installed. Just slide the tab with your finger, position the strap between the lugs, and release. No tools needed — it clicks in instantly.
Your Portofino should now be wearing its new strap. The whole process takes under a minute once you've done it once.
Everything you need to swap straps in one compact tool. Forked tip for spring bar removal, micro tip for fine work, and a pin pusher for bracelet links. Works with all standard spring bars.
About Delugs
A Strap Specialist, Not a General Store
Founded in Singapore, Delugs is dedicated to elevating watch ownership through the simple yet powerful act of strap changing. We believe straps are how a timepiece is worn, perceived, and enjoyed — and our mission is to make strap changing a lifestyle.
We work closely with watch brands to craft straps that complement their timepieces, and our direct-to-consumer focus keeps us closely connected with the watch enthusiast community. Each leather strap takes 4–6 hours to handcraft; our rubber straps are precision-moulded from FKM rubber.
How We Build
Quality You Can See and Feel
Handcrafted with Care
Every leather strap is handcrafted through over a dozen steps — cutting, splitting, skiving, stitching, edge painting, and quality inspection. No shortcuts.

Wear-Tested and Stress-Tested
Every product is worn daily by our team and put through rigorous durability testing before release. If it doesn't hold up in the lab and on the wrist, it doesn't ship.
Designed by Collectors, for Collectors
We're watch collectors who build products we want to use. Custom quick-release spring bars, CTS rubber straps, the Strap Finder — all born from our own frustrations as watch owners.
