Notes: The 4107 was made with an 18K rose gold case. The dial face uses Arabic/Stick numerals. The second hand is featured in a typical sub-location at the 6:00 mark.

Mechanism: The Hunter series of movements was introduced in 1923 and designed to replace the earlier Rebberg series. In 1935 Rolex complemented the design with the "Superbalance" component (for which they obtained a patent). The 10½ Hunter was named as 10½ is the size in lignes (23.7mm) and “Hunter” being the layout of the watch design, meaning that the winding crown was at 3, as in a hunter pocket watch (one with a lid that closed over the dial), rather than at 12 as in an open-face pocket watch. Rolex and Aegler made continuous improvements to this line of movements from 1923 when it was introduced until 1969 when it was finally retired

This late version of the Hunter was augmented to pass chronometer certification. The augmentations took the Hunter movement of the 1950s from 17 to 18 jewels. Like all Hunters, this movement has no date function. This version has the second hand in a "sub" or subsidiary location below the main dial. Later versions of the movement are known as Calibre 700.
