The watch features a black dial that gives visibility to concentric grooves that emanate from the centre and intersect across its surface.
The dial has gold numerals and hands to match a gold-plated stainless-steel case. A gold dot marks 12 o'clock.
An elongated third hand and inner ring that counts the seconds have been added for precise timekeeping. The time can also be read straight from the inner index track of the hour hand.
The watch features a neoclassical-style date hole and a dial protected by a 36-millimetre pane of glass made from hardened mineral.
It carries a high-quality Swiss 715 Ronda movement and comes with a navy Italian leather strap.
Named after the Spanish word for flat, the hugely popular Plano first launched at Dezeen Watch Store last summer. It features a mid-century-inspired dial and case that is only 6.7 millimetres thick.
"The Plano was influenced by a whole host of timeless predecessors," Squarestreet founder and designer Alexis Holm previously told Dezeen. "But it tips its hat towards mid-century dial designs, and there's a clear hint of Piaget in the case design."
Holm launched the brand in 2010, taking its name from the road it was founded on in Hong Kong creative Sheung Wan district.
The watches are produced in Hong Kong using locally sourced materials, but have a distinctly Scandinavian aesthetic influenced by Holm's Swedish heritage.
The Plano can be purchased from Dezeen Watch Store for £200.
