When Hiroshi Fujiwara turns his attention to a product, the ripple tends to travel far beyond its original niche. His latest project sees the Fragment Design founder put his stamp on one of Seiko’s most left-field releases of recent years – the Metronome watch.
First launched in 2022 by Seiko Instruments rather than Seiko’s main watch division, . Part of the appeal lay in its unusual provenance. Built by the arm of the company known for electronic components and traditional metronomes, it functioned as both a quartz wristwatch and a fully operational musical tool.


The watch features an integrated metronome adjustable from 40 to 208 beats per minute, alongside a pitch function cycling through six tones. For musicians, it is practical. For collectors, it is an anomaly – a reminder that Seiko’s reach extends well beyond dive watches and dress pieces. Limited availability outside Japan only sharpened demand.



Fujiwara’s Fragment Edition remains faithful to the original formula. Housed in a stainless steel case, the PA50-00B0 arrives in two colourways: white and black. The white dial swaps standard dark markings for red tempo indicators and blue BPM numerals, while the black version pares things back with crisp white detailing. Each model is signed “VA Fragment Metronome”.
