The 8th Asian Games (Thai: เอเชียนเกมส์ 2521) were held from 9 to 20 December 1978, in Bangkok, Thailand. Seiko released a few different versions for the Asian Games but it is hard to find any good information online.

Anyway this is a Seiko 7025-8030 with the "Bangkok 1978 Asian Games logo. A lovely gift from my wife ♥️

p.s Need to find the original bracelet, but for now this is a temp solution.
