Named after the Spanish word for flat, the Plano measures just 6.7 millimetres thick – making it the Scandinavian brand's slimmest watch to date.
The stainless steel case comes in matt black or polished gold, with a 36-millimetre glass lens made from hardened mineral. It also carries a Swiss 715 Ronda movement.
Squarestreet founder and designer Alexis Holm added the brand's signature concentric circles to the design of the watch face, which also references luxury Swiss watches of the mid-20th century.
"The Plano was influenced by a whole host of timeless predecessors," Holm previously told BestDealStore2Buy. "But it tips its hat towards mid-century dial designs, and there's a clear hint of Piaget in the case design."
The watches, which also have a 5ATM water resistance rating, are produced in Hong Kong using locally sourced materials, with Holm developing the designs to add a Scandinavian touch.
