no. 1 approach
[0048] based on figure 1 , figure 2 Now, the timepiece 1 of the first embodiment will be described.
[0049] Such as figure 1 As shown, the timepiece 1 is a wristwatch having a timepiece case 101 for accommodating a movement, and a timepiece band 10 attached to the timepiece case 101 . In addition, the movement accommodated in the timepiece case 101 may be a crystal movement equipped with a crystal vibrator, battery, motor, wheel train, pointer, etc., or may be a movement equipped with a mainspring, escape wheel, pallet fork, wheel, etc. Mechanical movements such as watches, hands, etc. In addition, a digital display device that does not have hands may be accommodated in the timepiece case 101 .
[0050]For the timepiece case 101 , a timepiece case made of general materials used in timepieces such as stainless steel, gold, platinum, titanium, etc. can be used. In addition, the timepiece case 101 may be formed of the same metallic glass as the timepiece band 10 described ...
no. 2 approach
[0086] refer to Figure 4 Now, the timepiece 2 of the second embodiment will be described. The timepiece 2 has a timepiece band 20 attached to a timepiece case 101 . The timepiece band 20 is configured to include a first band 21 and a second band 22 , one end of which is attached to a lug 102 of a timepiece case 101 . Like the first strap 11 and the second strap 12 of the first embodiment, the first strap 21 and the second strap 22 also have an elastic modulus of 30 GPa to 70 GPa, and an elastic limit of 2% or higher. And 20% or less of the material properties of the metallic glass of a single component. Therefore, specific examples of the metallic glass are also the same as those of the first embodiment.
[0087] The first band 21 and the second band 22 are each bent along the longitudinal direction of the respective bands 21 , 22 . That is, the first strap 21 and the second strap 22 have: base end portions 211, 221 mounted on the watch case 101; end portion; intermediat...
no. 3 approach
[0095] refer to Figures 6 to 8 Next, the timepiece 3 of the third embodiment will be described. The timepiece 3 includes a timepiece exterior member 300 having a timepiece case 301 and a timepiece band 30 . The timepiece exterior member 300 is integrally formed of metallic glass having material properties of an elastic modulus of 30 GPa to 70 GPa and an elastic limit of 2% to 20%. Specific examples of the metallic glass are the same as those of the timepiece bands 10 and 20 of the respective embodiments.
[0096] The timepiece case 301 includes a case body 302 formed in a substantially annular shape, and a dial 303 integrally formed in the case body 302 . Furthermore, the timepiece band 30 includes a first band 31 attached to the 12 o'clock side of the timepiece case 301 , and a second band 32 attached to the 6 o'clock side of the timepiece case 301 . Therefore, the timepiece exterior member 300 is a member in which the case main body 302 , the dial 303 , the first band 31...
