Presentation Our name “LabChime” comes from our identity. Our workshop is a laboratory (Lab) whose goal is to create, develop, manufacture and qualify watch gongs. The term “Chime” comes from English and refers to the sound of a carillon. Like a carillon bell, which has three bells, our know-how is based on three main axes: innovation, manufacturing, qualification. Skills Traditional know-how combined with current manufacturing, control and engineering techniques allow us to imagine, design and produce single-thread, two-threads gongs and chime gongs. In addition, we have the audacity to explore disruptive solutions in terms of sonorous elements. Our goal is to work for established watch brands, but also with those wishing to break the codes. We work in the field of gong restoration of both modern and old pieces. We we also collaborate with museums, as well as independent watchmakers. The laboratory LabChime Sàrl is a watch gong manufacturing workshop. The gongs are made manually, piece by piece. Today's demands inspire us to offer you the essence of craftmanship, associated with strict criteria of quality and reproducibility. LabChime Sàrl builds all quality control processes according to your needs. From the range of manufacturing until final sound control after tuning. You will have the assurance of compliance with your required criteria. Contact us As part of a possible partnership or any interest, we would be happy to get in touch!
