1. A wrist-worn electronic device comprising:
a housing including a bottom wall configured to contact a wearer's wrist and a side wall coupled to the bottom wall;
a bezel formed at least partially from electrically conductive material and positioned along an upper edge of the side wall;
an antenna including a first aperture and a second aperture, the antenna configured to operate in one of two operating modes including
a dual band mode in which the first aperture receives a first global navigation satellite system (GNSS) wireless signal at a first frequency band and is formed by a first portion of a circumference of the bezel, and the second aperture receives a second GNSS wireless signal at a second frequency band and is formed by a second portion of the circumference of the bezel, and
a single band mode in which the first aperture and the second aperture each receive the first GNSS wireless signal, the first aperture is formed by the first portion of the circumference of the bezel, and the second aperture is formed by a third portion of the circumference of the bezel located within the second portion of the circumference of the bezel; and
an aperture tuning network having an adjustable configuration wherein adjustment of the adjustable configuration changes the operating mode of the antenna.
