Ref. : FBLP.01.BH.21S / FBLP.01.BH.22S / FBLP.01.BH.23 / FBLP.01.BH.24SClasp FBLP.01. BH.21S continues in the spirit of the design of FBLP.01.BH19S and FBLP.01.BH.20S but it has a rather original security. Clasps FBLP.01.BH.22S and FBLP.01.BH.23 are bracelet clasps. Their particularity is in the blade. The clasp is engaged and closed with one hand. The model FBLP.01.BH.24S comes to us from watchmaking. Security works across the bottom of the box. The construction is quite complex but the security is high.
