The top three photos were lit with direct sunlight coming through a window. I flagged some of it off to create shadows and slivers of light to define the composition, and kicked some light in from the opposite direction using a small silver card. I wanted to light to be hard and used the bright areas to define important parts of the subjects.
Normally it would be difficult to hold the entire tonal range with this type of hard, candid light, but the extensive dynamic range of modern digital sensors, and the especially the Fuji X cameras, thrives in these situations. In the days of color film, shooting like this would have been near impossible to do. Today you can obtain a passable image even with a cell phone camera.
For the top shot of the inside of a watch I used an extension tube with the 60mm macro to come extra close.
