Seth Thomas Wall clock

I inherite this wall clock from my father in laws house. It was bought more than 30 years ago from an antiques dealer in Madras in southern India. It was likely from one of the residences or offices of the British during the colonial era. Interestingly the face is clear glass allowing one to see the movement. I've tried looking for similar clocks online to establish the year that the clock might have been made in but can't find any indication of this anywhere on the interior or exterior of the clock.theres just a tiny "4G" inscribed on one of the parts. If anyone knows something about this piece I would love to know more about it !
