Method for soldering a first component (10) made of ceramic, and a second component (20) made of metal alloy, for producing an element (100) of structure or cladding for timepieces, the first is chosen component (10) a ceramic based on zirconia, and, for the second component (20) a titanium alloy, a first housing (4) is produced in the heart of the first component (10), set back from a first surface (1) in a junction zone (3) with a second surface (2) of the second component (20), we place the solder (5) on this first surface (1) and in each housing (4), we position the second surface (2) in accordance with the first surface (1) to constitute an assembly, heating is carried out under a controlled atmosphere of said assembly above the melting temperature of the solder (5), to perform its soldering at of the junction zone (3).
