A confusing date on family heirloom

[jordant7]

This piece of paper was found in a family pocketwatch. The watch itself seems to be dated to the 1830s, according to stamps on the silver casing, and the general design (it's a verge fusee). So even though this signature seems to say '1667' or something, that doesn't seem possible. Could the paper predate the watch? or is is that not a date at all

[Raybistre]

Old watches sometimes have these papers inside them. They refer to the watch being serviced or repaired. Its not a date. The number would have some relevance to the man who serviced or repaired the watch.
