The Dynamo

Driven. Dynamic. Unrelenting.

Dynamo is blue tungsten worked into a hammered finish, kinetic even when it sits still.

Some men run on willpower. You run on something that does not have an off switch. While the rest are resting, you are already three moves ahead, and that is why you win.

A ring for the man who never runs out, and for the one who is swept along in the best way.

Rest is for the finished. Wear the Dynamo.

Free tracked delivery, worldwide
Lifetime warranty on every ring
Ships in a Rokkard gift box

Machined from a single block of tungsten carbide and inlaid by hand. Scratch-proof, hypoallergenic, and backed for life.

Wipe with a soft cloth. No plating to wear, no polishing required.

Free worldwide shipping. In-stock sizes dispatch in 2–3 days; made-to-order sizes take 2–3 months. 30-day returns.

Order our free ring sizer, or use the size guide. Tungsten cannot be resized — we exchange instead.
