The Bangkok entrepreneur turned his office into a private gallery of roughly 1,000 watches and more than 1,000 clocks, beginning with a Seiko bought on instalments.
Who is Prasart Vidhayapat?
Prasart Vidhayapat is a Bangkok entrepreneur whose business card carries two identities: his corporate title and “owner of private watch gallery.” He founded and runs a stationery supplier, then filled the company's office with one of Thailand's most extensive private collections of watches and clocks.1
The office is also the gallery. Glass cases line the walls, displays spill into the reception area and watches sit in boxes, drawers and pouches around his desk.
How did Prasart Vidhayapat make his money?
Vidhayapat built his financial base through the stationery-supply company he founded and operates in Bangkok. The business provided the long-term platform for a collection assembled over roughly three decades, not a single windfall.1
That timeline matters because his first important watch was not an easy purchase. He bought a Seiko Sea Lion M88 in four monthly instalments. It remains part of the collection even though its monetary value is modest beside the pieces that followed.
Inside the 1,000-watch collection
A 2013 visit counted about 1,000 watches and more than 1,000 clocks. The range is unusually broad: vintage pieces, modern Japanese watches, coin watches, pocket-watch conversions, ship clocks, railway clocks and high-horology references from Switzerland.1
The gallery is arranged partly by brand and partly by theme. One Audemars Piguet display includes a Star Wheel and an early Huitième tantalum chronograph. Elsewhere sit Patek Philippe Naviquartz chronometers, Grand Seiko pieces and a Rolex King Midas that Vidhayapat wore for the profile.
A collection built for discovery
The defining trait is variety rather than a single trophy brand. Vidhayapat bought across price levels and eras, which makes the rooms read like a personal museum of timekeeping rather than a row of status watches.
Four alarm systems protected the office collection at the time of the visit, with other watches stored at home and in a bank vault. The security is serious, but the first Seiko still explains the collection best: buy what creates fascination, keep it, and let decades of curiosity do the rest.1
