Hello Maheshp.

The options that I know of are these.

1.  Use a smaller aperture to increase depth of field.

2.  Use a tilt-able axis lens (perspective control lens).

3.  Reduce the angle to less than 45 degrees so that all the face of the watch falls within the available depth of field.

4.  Focus stacking.  Take a series of images with different subject focus planes and integrate them with software to increase apparent depth of field in the combined image.

Maybe others here will have some other ideas.  Good luck with it.

Some say that those of us who like to talk about cameras should instead go and take pictures. I say we should go and also take pictures.

In addition to the above points, you may want to try a wider angle lens. The 105 macro at its closest focusing distance will offer a pretty shallow DOF even if it is stopped down.

If you have the option, move a bit further away from the subject.

If you want to try the focus stacking alternative, for your specific requirement, you can try the following technique: This is not feasible in all scenarios, but may work for you.

The link you have shared is 0.5MPix 300dpi image good for web

If you want your output at such small size there is one more thing you can do i.e. crop it. (I would call it fake it)

You increase cam to subject distance (Keeping sweet F8) till you get required DOF and then crop to required size.
On a 20Mpix sensor this will be easy.

Best accessory of camera is 3" behind it,
And mine needs an upgrade. . . ;)
