Stepping up in Storm's range
The Porto sits at the point where a watch becomes an accessory in the fullest sense — the rigid bangle bracelet and the rectangular case read as a single object rather than a strap with a head attached. At 20mm wide and 35mm lug to lug, the case is compact enough to stack or wear alone without bulk, and the starkly unadorned black dial keeps the eye moving across the piece rather than stopping at the time. At 73g the bracelet has enough presence on the wrist to feel considered, and the all-steel construction means it holds its shape permanently — no softening, no stretching, no adjustment needed over time.

Learn more about Storm
Storm was founded in London in 1989 and spent the next decade doing something few watch brands attempt: treating the case as sculpture rather than a container for a dial.
The house style is immediately identifiable — mirror-polished steel, faceted and asymmetric cases, dials with no numerals at all, and a fondness for finishes that make the whole watch look like a single machined block of metal.
Some of the designs abandon conventional time display entirely, using rotating discs, hidden apertures or coloured mirror crystals that only reveal the time at certain angles. The Remi and Zorex lines have carried that idea for years.
The brand designs and produces its own watches rather than licensing the name, and sells through its own stores and jewellers, mostly in the UK and Europe.
Movements are quartz throughout. The point has never been the mechanics; it is that a Storm watch does not look like anything else in the window, which after thirty-five years remains a fair claim.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Showering yes, swimming no. 50m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.
Water resistance explainedWill the glass scratch?
It can, over time. Mineral glass handles daily wear but will pick up fine scratches that sapphire would not.
Sapphire, mineral and acrylic comparedDoes it need a battery?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
Quartz, automatic and solar comparedWill it fit my wrist?
Lug-to-lug is 35mm, which suits wrists from roughly 15cm (6 inches) upward.
Lug-to-lug decides fit more than case diameter does.
