4. The modular assembly as recited in claim 3 wherein the additional strap attaches to the strap using a magnetic element.

5. The modular assembly as recited in claim 1 further comprising a third base unit of a third electronic device, the third base unit comprising:

a third functional element configured to perform a third set of functions different from the first and second sets of functions; and

a third enclosure housing the third functional element that defines a fourth attachment coupling to which the third attachment coupling is configured to attach.

6. The modular assembly as recited in claim 1 further comprising an additional strap unit configured to couple with either of the first or second base units and having a different strap characteristic than the strap unit.

7. The modular assembly as recited in claim 6 wherein the strap characteristic is an aesthetic characteristic.

8. The modular assembly as recited in claim 7 wherein the aesthetic characteristic is at least one of a surface texture, surface finish, a color, a shape, a material, or a structural configuration.

9. The modular assembly as recited in claim 6 wherein the strap unit and the additional strap unit are configured to perform different functions.

10. The modular assembly as recited in claim 6 wherein the third attachment coupling and an attachment coupling of the additional strap unit have at least one of different attachment forces or different break forces.

11. The modular assembly as recited in claim 6 wherein the strap unit and the additional strap unit each include a functional feature, wherein the functional feature of the strap unit is configured differently from the functional feature of the additional strap unit.

12. The modular assembly as recited in claim 1 further comprising an additional strap unit configured to couple to the first base unit in a third configuration and the second base unit in a fourth configuration wherein the additional strap unit has a different aesthetic characteristic than the strap unit.

13. The modular assembly as recited in claim 12 wherein the aesthetic characteristic is at least one of a surface texture, a surface finish, a color, a shape, a material, or a structural configuration.

14. The modular assembly as recited in claim 1 wherein the first functional element and the second functional element each include at least one of a display, a button, or a controller.
