In March, Citizen lavishly kicked off its 100th anniversary celebrations at BaselWorld 2018 in Switzerland.
The party is not over yet for the Japanese watchmaker, now staging an exhibition in Bangkok to mark the milestone at The Gallery in The Emporium shopping complex until Tuesday.
A selection of vintage models along with the latest collections are on display to represent the diverse range as well as horological technologies and achievements over the 100 years.
Cryston Solar Cell (1976), the world's first light-powered analogue quartz watch.
Founded in 1918 as Shokosha Watch Research Institute, the company changed its name to Citizen to convey its mission to make precise timepieces to citizens around the world. The debut pocket watch bearing the Citizen brand name then came out in 1924.
This year, the nostalgic pocket watch has been revived to showcase the Calibre 0100, an Eco-Drive movement with annual accuracy ± 1 second. The precise time is given based on an internal mechanism with no reliance on time signals from radio towers or GPS satellites.
The original pocket watch and the Calibre 0100, which marks the start of Citizen's next 100 years of watchmaking, can be viewed at the exhibition.
Also on display are the company's world firsts including a light-powered analogue quartz watch, a multi-band radio-controlled watch and a light-powered satellite synchronised watch.
The Eco-Drive technology was devised in the 1970s as an alternative energy source to a battery, which powered quartz watches popular at that time.
Batteries require replacement and environmentally-damaging disposal whereas Citizen's technology runs using light from any source, such as natural, artificial and even dim light.
Launched in Thailand this month, the 100th anniversary limited editions feature the proprietary light-powered technology and designs in black with gold accents to express the concept of "inhaling" light to "exhale" time.
The commemorative models include the oversized Satellite Wave GPS housed in a 48.5mm super-titanium case and priced at a whopping 140,550 baht.
