here's a couple taken using natural light.
this one using fuji x10.
f/2, 1/50s, iso100.
blocked it all around, and only allowed the sunlight to enter from the top right.
then a white envelope was used to bounce some back to highlight the ridges.

this one d7000 + tamron sp90.
f/3.5, 1/80s, iso1600.
not enough depth of field, cos not enough light, and i didnt want to go above iso1600...but ok la.
just placed it on top of my dinner table glass top for the reflection.

i since sold off the tamron sp90 cos not happy with it, and replaced with a nikon 40mm macro.
am actually pretty lazy to shoot watches, cos lazy to set up the lights etc.
anyway the 40mm macro last i shot was this...a 1/18 ford mustang bullitt.
f/22, 1/30s, iso200.
lighted with a flash on each side...tho would've been nicer with an extra one for the back.
