HI
the wood you have is most probably "Ramin" from the tree Gonystylus bancanus from malaysia.
It has characteristics and uses similar to those of beech, but yellowish. Little breaking and light enough (density 0.7), it has a good resistance to bending. it is very easy to cut tennons and mortices in it, but hard to polish and wax in my own experience, may I add IMHO that a clock frame deserves better.
cheers
