Universal Geneve “Nina Rindt” Bracelet and Strap

The Universal Geneve 885103/02 “Nina Rindt” can be found on one of two bracelet and clasp designs, as well as a leather strap.

Bracelet
Earlier pieces can be found paired with a Gay Freres double-grain beads of rice (DGBOR) bracelet, and clasp with shield logo design (see below). Given how few these are, it is difficult to say which, is any, are original to the watch.
The inside of the clasp is stamped
BREVETE STEELINOX
Followed by the Gay Freres logo and UG stamp
Then SWISSMADE
And lastly, the quarter (1-4) and last two digits of bracelet production.

On later pieces we see the clasp with logo of the U-only, within a box, paired with a bracelet that is not exactly double-grain, but roughly similar in appearance.. The inside of the clasp is stamped
STAINLESS STEEL
MADE IN U.S.A.
followed by the Universal Geneve logo, with shield though.
I do not know the maker of this bracelet.

Endlinks stamped ‘UW’ are generally accepted as the correct links to pair with the Universal Geneve 885103/02, though we see a number of pieces using endlinks of different shapes that are not stamped.

I have seen examples of JB Champion bracelets in use with Ninas. Others have noted, however, that the JB Champion endlinks do not fit Compax cases. Given this, it is unclear whether those bracelets were original to the Nina, or simply an option that some owners purchased after acquiring their watch.

Strap
Another rare find is an original Universal Geneve strap and buckle. The original strap with be found in patterned black leather, with the pointed U logo on the buckle.
