TF Est. 1968 shows up on men’s shirtsleeves. Enlivening overly strict suits, drawing all eyes and celebrating their difference, “Tourbillon” cufflinks proclaim their watchmaking inspiration. At the heart of a steel cage coated with carbon motifs, a mechanical movement beats to the rhythm of the wearer’s every move. Through a transparent glass similar to that on watches, one succumbs to the temptation of admiring the watch manufacturing expertise on show. In design terms, the curved stem serves to lock the cufflink in place and prevent it from pivoting. A clever, direct and precise spring clasp system holds it firmly in place on the shirt. These particularly robust accessories are also watertight and shock-resistant. Get ready for other variations that are in the pipeline.
