“Water-resistance tests” Follow Lesson no. 6 by Maestro Tarondo

lesson N°6

Excellence and quality tests

In the last watchmaking lesson, Antonio told us about tests to be carried out to check the chronograph's performance and characteristics. The first test is conducted with a machine working with an air-operated device. The watch is subjected to lowered pressure conditions and tested at various barometric levels. Only a perfect mechanism completely sealed off will be able to resist the pressure change with no damage or slowing down. The next (and the best) step is to make sure the watch is fully water resistant by dipping it into water. If the encasing procedure has not been entirely successful bubbles will form and try to reach the surface. If oxygen bubbles do not appear during the test, the watch may be considered fully functional, with optimal resistance against atmospheric agents.

Only when perfection is attained at all stages of production will the watch (rightly and deservedly) pass all tests.

The strap: elegance and style through to the very last stage!

Attaching the strap is the last of the procedures at the Tarondo workshop. Antonio explains that all stages in the process must be carried out with great care and attention, Manually, using a small screwdriver, the pins that hold the strap to the case are inserted. The watch is now ready to be worn.

Made in Italy means a focus and beauty and on style. And that includes this stage in the assembly process. The style is quite unique.

Artisan watchmaking and young people

Watchmaking is anything but easy! But Antonio loves his job and wouldn't want to do anything else in the world. Every new watch that leaves the Tarondo workshop is an achievement one can take pride in. Artisan watchmaking is a challenge. Absolute perfection is a statement in itself. Man competes with the absolute precision of time itself!

The learning for all this never stops! Youngsters will find there are many opportunities for experimenting with new ideas and seeing them come to fruition in a fairly short time. This is why we see watchmaking as a great opportunity for the creative talents of the future.
