Leonardo Collection
Creativity, Ingenuity, Innovation, Aesthetics
They are the links between art and science, technology and beauty. With the Leonardo Collection, Hirsch overrides contrasts and contradictions. Leonardo bracelets overcome the limits of materials.
So far, owners of watches with integrated bracelet attachment were restricted to original watch bands. Leonardo, however, combines aesthetics and design with innovative technology. Now it is up to the customer to make the choice - and decide for the future.
You will be able to attach any bracelet from the Hirsch Leonardo collection to the watch cases of the most renowned watches from the Luxury, Sports and Fashion segments. The Leonardo bracelet connects to the noble case of the watch as if custom-made for it. The prestigious character of exclusive watches is enhanced even further by the perfect processing, the sporty elegance of design and the innovative technology of Leonardo watch bands.
The most striking design elements that complement any sporty chronograph perfectly are the square tip and the wide loop. They underline the modern and sporty character of the Leonardo bracelets and give them a sturdy look. The loop also secures the bracelet. Leonardo is ahead of its times. Hirsch turns visions into reality and combines sporty elegance and aesthetics of this unique bracelet with the revolutionary innovation of the variable, integrated band attachment.
The Difference
The Leonardo bracelet differs from conventional watch bands in that it combines with the watch case as if specially made for it. This integration between bracelet and watch creates a single work of art, a beautifully rounded unit that fits closely around the wrist - like a bracelet - and thus enhances the aesthetic character of the watch. Also impressive is the power of the bracelet, from the attachment to the centre, clearly emphasising its robust and sporty character.

Attachment System
The attachment area of the bracelet allows to be fitted on to a wide variety of watch case forms. In all there are 8 possibilities for positioning and adjustment to integrated attachments on watch cases.

The soft insert is injection moulded from elastic plastic (NBR). Because of the elasticity of the material this part can be adjusted to the various radii of different watch cases. The shape of the attachment extends under the case and prevents any slipping through. The attachment is incorporated into the bracelet and, within the finished product, it is no longer visible from the outside. Because of the various positioning possibilities for the spring bar, the hard insert guarantees the ideal distance between the bracelet and the watch case, which cannot be achieved by the soft insert alone.

In all there are 8 positioning options for the spring bar (required diameter: 1.5 mm); the distances are being altered horizontally and vertically by turning in 0.5 mm stages respectively.
Assembly Guide
Using the Instrumento (no longer available), determine the correct position for the insert and for the spring bar. Place the Instrumento with the attachment against the watch case. The two pins of the Instrumento insert simulate the possible positions of the spring bar on the Leonardo bracelet. If neither of the pins fits in the existing position into the drill hole on the watch case, their position (distance and height) can be changed by taking out the insert, turning it and reinserting it.
The insert contains two oblique drill bores. Because the insert has four sides (marked as I, II, III, IIII), this provides 8 different positioning possibilities. By turning the insert the distances can be altered horizontally and vertically in 0.5 mm stages.
Once you have found the correct position for the spring bar (position of the insert, pins either on top/underneath or in front/behind), press out the insert of the Leonardo strap from left to right using a Fitting Tool (or one of the pins from the removable Instrumento attachment).
Then place this insert in the same position (marked I, II, III, IIII) as the insert of the Instrumento and press it into the Leonardo watch band again from right to left.
Now slide the spring bar (required diameter: 1.5 mm) into the correct drill hole (depending on which pin of the Instrumento insert simulates the right position). The same position naturally fits with both parts of the bracelet.
You can now assemble both parts of the bracelet with a Fitting Tool. If the bracelet does not sit perfectly against the watch case, detach it once again, alter the position of the insert by one 0.5 mm stage, and assemble once more. Clue: If position I (top) doesn’t fit perfectly, move Hard Insert 0.5 mm towards Position III (top) to obtain the desired result (Fig. below).
FAQ
What is the relation between the 4 positions of the hard insert?
The positions of the bores change - depending on the turn - in steps of 0.5 mm. With the two bores opposite each other at a slant angle, the hard insert covers 8 possible positions of the spring bar (required diameter: 1.5 mm). A look at all the eight positions (Fig. right) shows how close the individual positions are to each other.
What distances does Leonardo cover between the spring bar and the watch case?
The distance between the spring bar and the watchcase (on the inside of the lugend) ranges from 4.5 mm to 5.5 mm (with +/- 0.5 mm tolerance) depending on the position variant of the hard insert. If the distance between the spring bar and the watch case exceeds these dimensions, the Leonardo watchband no longer fits.
What watches (depending on the model) does Leonardo fit?
Leonardo bands suit watches from Breitling, Bremont, Calvin Klein, Festina, IWC, Jaques Lemans, Omega, Rolex, Seiko, Tissot and many more...
What watches does Leonardo not fit?
- Rectangular watch cases
- Watch cases with bevelled edges
- Watches with bores too close to the watchcase (less than 4.0 mm)
- Watches with bores too far away from the watchcase (more than 6.0 mm)
- Watches with screwed bars
