Pocket Watches

The mechanical complexity of the repairs thrills El Cronometrista

These little marvels require particularly sensitive repairs, as they have avery definite style depending on when they were made and this style must always be respected for proper restoration.

The mechanical complexity of many of these watches, like repeaters, perpetual calendars, etc., gives me a thrill.

El Cronometrista is a specialist in chronometer escapements, such as Duplex, Virgule, Cylinder, Swiss lever, unusual escapements and other rarities.

Singing Bird Boxes

From replacing the feathers or the leather or valves of bellows, to making any defective part.

Singing bird boxes, pocket watches and chronometers are my speciality and I have devoted by working life and career to them. Feeling the satisfaction of making a high-quality machine work perfectly again after being damaged or broken is my reward and a stimulus to tackle new, complex reconstruction projects.

I have never been scared by mechanical complexity; instead, I am fascinated by discovering new complexities and solutions for what was made with much less advanced technology and I ask myself how the great masters would do it today.
