FIG. 1 shows a watchband 10 connected to opposite ends of a wearable electronic device 100, such as a wristwatch or a health tracking device, which can be attached to a user's wrist by the watch band 10 wrapping around the user's wrist.

Referring to FIG. 1-FIG. 8, the watch band 10 in accordance with an embodiment of the present invention comprises a connector 20 comprising a first hole 22 and a second hole 24 arranged at opposite ends thereof in a length/longitudinal direction of the watch band 10, a first band 30 connected to the first hole 22 of the connector 20 and a second band 50 connected to the second hole 24 of the connector 20.

The connector 20 further comprises a connection beam 26 located between the first hole 22 and the second hole 24, and a pair of side walls 28 extending in the length direction of the watch band 10. The connection beam 26 extends between the side walls 28 in a width/transverse direction of the watch band 10. The first hole 22 and the second hole 24 are enclosed holes, which means the holes having enclosed circumferential edges surrounding the holes. Referring to FIGS. 8, 13 and 13B, the side walls 28 of the connector 20 have inner surfaces 28a configured to contact with the user's wrist. Preferably, the inner surfaces 28a are curved for fitting with the user's wrist better. The connector 20 may be made of metal or plastic material.

The first band 30 comprises a first connection member 32 configured for being connected to an end of a wristwatch or a health tracking device, a free end section 34 and an extension section 36 connected between the first connection member 32 and the free end section 34. The free end section 34 is extendable through the first hole 22 to be fastened to the extension section 36 by VELCRO-type hook-and-loop fasteners, which facilitates to provide a user-adjustable size.

Referring to FIGS. 2 and 4-8, the extension section 36 is flexible and comprises a base layer 362 and a fixing layer 364 for engaging with the free end section 34. The base layer 362 is configured for contacting with the user's wrist. The base layer 362 defines a length direction extending from one of the first connection member 32 and the free end section 34 toward the other of the first connection member 32 and the free end section 34, a width direction perpendicular to the length direction, and a depth direction perpendicular to both the length direction and the width direction.
