wherein the cover member comprises a cover main body, an outer circumferential cover section and band attachment sections,

wherein the cover main body, the outer circumferential cover section and the band attachment sections are integrally formed, and

wherein the attaching the cover member to the back cover comprises attaching the cover main body to a second side of the back cover opposite to the first side of the back cover such that:

at least a portion of the outer circumferential cover section and at least a portion of each of the band attachment sections are provided on the first side of the back cover to cover an outer circumferential surface of the case member; and

a space is provided between the outer circumferential surface of the case member and an inner end surface of each of a pair of attachment projections of the each of the band attachment sections corresponding thereto and an upper inner end portion of the each of the pair of attachment projections is arranged in contact with a lower rim of an outer circumferential portion of an exterior case attached to an upper outer circumference of the case member.

2. The manufacturing method according to claim 1 , further comprising:

arranging a ring-shaped parting member on an upper opening of a main body case of the case member;

attaching a glass and a packing to the main body case to press the ring-shaped parting member against the main body case by the glass to fix the ring-shaped parting member; and

attaching an exterior case to an upper outer circumferential portion of the main body case.

3. The manufacturing method according to claim 1 , further comprising:

arranging a buffer sheet between the module and the first side of the back cover,

wherein the first side of the back cover is attached to the case member after the buffer sheet is arranged between the module and the first side of the back cover, and

wherein attaching the first side of the back cover to the case member comprises attaching the first side of the back cover and an undersurface of the main body case with a waterproof ring between the back cover and the main body case by a plurality of screws.

4. A manufacturing method for manufacturing a case, the manufacturing method comprising:

attaching a first side of a back cover to a case member; and

attaching a cover member to the back cover,

wherein the cover member comprises a cover main body and band attachment sections, and

wherein the attaching the cover member to the back cover comprises attaching the cover main body to a second side of the back cover opposite to the first side of the back cover and attaching the cover member such that at least a portion of each of the band attachment sections are provided on the first side of the back cover to cover an outer circumferential surface of the case member in a state where a space is formed between the outer circumferential surface of the case member and an inner end surface of each of a pair of attachment projections of the each of the band attachment sections and that an upper inner end portion of the each of the pair of attachment projections is arranged in contact with a lower rim of an outer circumferential portion of an exterior case attached to an upper outer circumference of the case member.

5. The manufacturing method according to claim 4 , further comprising:

arranging a ring-shaped parting member on an upper opening of a main body case of the case member;

attaching a glass and a packing to the main body case to press the ring-shaped parting member against the main body case by the glass to fix the ring-shaped parting member; and

attaching an exterior case to an upper outer circumferential portion of the main body case.

6. The manufacturing method according to claim 5 , further comprising:

inserting a module into the main body case,

wherein the first side of the back cover is attached to the case member after the module is inserted into the main body case.

7. The manufacturing method according to claim 6 ,

arranging a buffer sheet between the module and the first side of the back cover,

wherein the first side of the back cover is attached to the case member after the buffer sheet is arranged between the module and the first side of the back cover, and

wherein attaching the first side of the back cover to the case member comprises attaching the first side of the back cover and an undersurface of the main body case with a waterproof ring between the back cover and the main body case by a plurality of screws.

8. A manufacturing method for manufacturing a timepiece, the manufacturing method comprising:

the manufacturing method according to claim 1 ; and

attaching timepiece bands to the band attachment sections of the cover member.
