Alexander Ian Loh, Founder
springsprangsprung_arcturus

Arcturus Watches was founded in 2017 on the belief that well-designed, top-quality watches should be accessible to everybody this side of the galaxy. 


Hailing from sunny Singapore, our designs draw on the island-state’s multicultural melting pot for inspiration. Our ethos is to create stunning timepieces with a signature dash of Singaporean charm. Named after the brightest star in the northern celestial hemisphere. Arcturus encapsulates our hopes to become a supernova in the microbrand watch universe, and establish Singapore on the world’s horological map.


Every Arcturus timepiece is intentionally designed from scratch. From the curve of the case to the shape of the hands, nothing is off-the-shelf. Each model draws from cultural and architectural inspiration—particularly from Singapore—and reinterprets it through a mechanical lens.


The name “Arcturus,” a bright star in the Boötes constellation, reflects the brand’s guiding philosophy: to be a steady, luminous presence in the independent watch world—rooted in place, but reaching far.
