Help needed to identify PAM390 origin

[boonper]

Hi Experts, I got this watch as part of a sale trade. Am trying to pass this watch on and it might help if the factory origin & version can be identified.

Please help to chip in if possible and let me know if any other pictures is required. Thanks you so much in advance!
