Thank you to The Watch Lab and Mr. Vigneri for bringing my grandfather’s watch back to life. This 1960s timepiece was completely rusted and had already been opened and deemed irrecoverable.
I am truly blown away by the level of craftsmanship, the polishing and sculpting work are outstanding. On top of that, I was kindly offered a beautiful bag for the watch and a generous discount on the bracelet.
I couldn’t be happier with the final result. Thank you so much.

J’ai appelé pour avoir des renseignements, mais la personne que j’ai eue au téléphone n’était pas du tout agréable ni joviale…ce qui donne pas envie de faire appel a leurs services. Dommage

J’ai fait changer la pile de ma montre Ebel. Joli petit atelier, le Monsieur est charmant et très compétent, tant pour l’efficacité que le conseil.

Montre LONGINES déposée pour une révision complète et polissage après 10 ans sans entretien. La montre m'est revenue comme neuve. L'horloger a fait du super boulot ! Merci encore Costya. Je reviendrai sans problème...
