SYE Cannonball GMT Tulsa – Precision Meets Road-Ready Elegance

Introducing the Cannonball GMT Tulsa, a bold and refined timepiece designed for those who chase freedom and explore the world’s most iconic routes in style.

2 years warranty: The warranty for SYE watches is two years from the date of shipment.
It does not cover any damage on any part of the watch resulting from abnormal use, lack of care, negligence, accidents, incorrect use of the watch and non-observance of the instructions provided by SYE [Start Your Engine].

Unlike your teeth, your watch doesn’t need daily cleaning.

But if you feel it’s time — or if the case really needs it — simply grab a soft toothbrush (yes, the trusty old kind), and gently clean the case using mild soapy tap water.

Then, dry it thoroughly with your softest cloth to bring back its shine.

Water Resistance: Your SYE MOT1ON is water-resistant up to 50M (5 ATM).

In practice, this means the case can handle splashes, light rain, or everyday moisture — but it’s not suitable for bathing, showering, swimming, or diving.

And guys, let’s be clear: leather straps and water don’t mix — keep your watch out of the bathroom.

Water resistance is ensured by special seals (gaskets), but over time, natural aging or accidental impacts can affect their performance. To maintain optimal protection, we recommend having your watch checked annually.

Fastback™ Straps – Made to Endure

Crafted from premium leather, our Fastback™ straps are built to last. To keep yours in top shape:

• Avoid water: no baths, showers, swimming, or seawater.
• Keep away from creams, perfumes, and sprays.
• Remove before household or DIY tasks.

Each strap is unique and will develop its own patina over time — that’s part of its charm.

With daily wear, natural leather straps typically last 6 to 12 months, though our first Fastback™ strap is still going strong after 4 years.

All straps feature REACH-compliant leather linings, though rare skin reactions may occur.
