Robert Belcher Antiques has dated this Antique Brass Pocket Compass to the 1910s.

This complicated precision instrument has a folding case with a glass aperture and, when opened, reveals an adjustable viewing lens which magnifies for very accurate vernier readings of the dial.
The compass also has a sliding side button for locking the dial for not in use and a side clamping mechanism for locking the rotating bezel with its glass fronted indicator.

The outside of the case is stamped around the edge with pole directions and degrees. The compass also has a large folding loupe for attaching and carrying.
This compass could have been for military use or, most likely, a high quality personal piece for an adventurous traveller.
The compass is in excellent working condition.
