Hirsch Curved Straps Information

[himmelblau]

Hirsch curved straps use the Hirsch Leonardo strap attachment:

There are 8 different positioning possibilities for the spring bar as there are two opposite bores in the hard insert. The position of the bores change, depending on the turn, in steps of 0,5 mm. The distance from where the Leonardo bracelet is attached to the spring bar ranges from 4,5 mm to 5,5 mm (with +/- 0,5 mm tolerance). If the distance of the bore to the inside of the leg on the watch exceeds these dimensions, the Leonardo watch band no longer fits.



Determination of the insert position

In the first step you need to determine the position of the hard insert in relation to the watch case. With the HIRSCH Leonardo Instrumento this can be done quite easily.


Attach the Instrumento with the correct attachment in the respective width to the watch case. The two pins of the Instrumento insert indicate the possible position of the spring bar of the Leonardo watch band.


If none of the pins are suitable for the bores in the watch case in the current position, they can be adjusted in their position (distance and height) by removing, turning and reinserting the insert of the Instrumento. By turning the insert the distance will be changed horizontally and vertically in steps of 0,5 mm resp. 0,1 mm.

Assembly of the watch band



After finding the correct position of the insert (pins either up/down or front/back) remove the hard insert of the Leonardo watch band by pushing from the left to the right.

Bring this hard insert now in the same position (marked I, II, III, IIII on the insert) as the insert of the Instrumento and reinsert it into the Leonardo watch band from the right to the left.

Now insert spring bar (1,5mm) in one of the two bores (depending what pin of the Instrumento simulated the correct position). The same position is of course suitable for both pieces of the watch band.

You can now attach both pieces of the watch band easily to the watch case with a spring bar tool.

Thank you very much for the info, I tried unsuccessfully to put one on and got so frustrated I was ready to set them on fire.
