Our History
JJ Monteiro company was created in 1984, initially as an individual business by José de Jesus Monteiro, initially dedicated to watch repair. Allied to this service, the need arose to supply parts for movements and for the watches themselves, which came to satisfy the demand.
Since then the company has grown and also expanded its product offering, including all types of accessories and tools for watches, extended to the gold storage area in 1995. The company became a partnership in 2001, taking another step in its global growth.
In 2007 we opened a space on the Internet, in a technological era where digital became indispensable, offering a reference to our customers.
In 2025, we continue to improve this initiative and strengthen our reference in the sector! Today we have a range of products and services that aim to make watchmaking more accessible to everyone, also providing excellent technical assistance.
