Frequently Asked Questions
How long does it take to arrive?
Each custom timepiece is hand built To ensure the highest possible standards, we have a lead time of 3 - 4 weeks from the date of order to delivery. This allows us to carry out the necessary quality control procedures and ensure that your watch is made to your satisfaction.
All orders placed through our website are subject to the given lead time even if the item is shown as "In stock".
Each watch is assembled by hand piece by piece in a completely handmade way by an expert with more than 10 years of experience.
Are the watches waterproof?
Our watches are designed with a water resistance rating of 5 ATM, which makes them suitable for everyday use and able to withstand splashes or brief immersion in water.
However, they are not intended for swimming or taking baths.
To ensure the longevity and optimal performance of your watch, we recommend avoiding prolonged exposure to water
Will I receive tracking?
Yes - once your watch is shipped, you’ll receive a tracking link to follow its delivery.
How do I start and wind my watch?
Most automatic watches need an initial wind.
Turn the crown clockwise ~40 times to fully wind the movement. After that, wearing the watch regularly will keep it powered.
For mecaquartz chronograph models (VK63), no winding is required - they run on a battery.
