There were two varieties of bracelets original to the Mido ref 5907.

Bonklip-style
The first style seen on the Mido is the Bonklip, manufactured by B.H. Britton and Sons. This bracelet is found on both early and late batches. We see the Bonklip-style as the most common the Mk 1 pieces, but also on the Mk 2, and is not clear if it was a possible original bracelet for both periods, which would be more accurately determined by comparing the date stamp to the serial number. Given how inexpensive these bracelets are, it would not be unusual for these Bonklip-style bracelets to have been purchased later and added to an earlier piece. Oh, and how do I put this delicately….this is an awful, awful bracelet to wear. 😀

While a number of companies made this style of bracelet (also referred to as “bamboo bracelets”) during the production period of the Mido ref 5907, there is no stamp indicating the maker of the Mido bracelet, which I would expect to find if the bracelet was produced by either Bonklip, Gay Freres or Krementz. It is more likely that this was produced by another smaller manufacturer.

The “buckle” on the Bonklip-style will have a Mido stamp with the quarter and date on one side, and the words “STEELINOX” and “SWISS MADE” on the other. These were not expensive bracelets, and not surprisingly, the quality of the stamping varied.

I have seen one later bracelet (1967), included on a 5907, that appears not to have the “STEELINOX” and “SWISS MADE”. Given the spread of years in which these were ultimately sold, it is not surprising to see bracelets from a period later than the production of the 5907.

Mesh
The second style of bracelet found on the Mido reference 5907 is mesh, found primarily on Mk 2 batches. Again, being relatively inexpensive, a mesh bracelet may have been added later to a Mk 1 piece. There is a Mido stamp on the buckle, but as with the Bonklip-style bracelet, no maker’s mark. These mesh bracelets do not indicate production date.
