Sinn 356 PILOT Classic AS EvsEcho/Neutra Cristallo Professional Diver 500m

The Sinn 356 PILOT Classic AS E is praised for its excellent legibility, clean bicompax dial, and strong lume, with owners appreciating its fit and finish and attractive gradient dial. The Sellita SW510 BH b movement is noted as reliable, and chronograph functions are responsive, with accuracy reported within COSC parameters at +5 seconds per day. The 38.5mm case, particularly with the domed acrylic crystal, is described by some as wearing tall and appearing "tubby" on the wrist due to its 15.6mm thickness, though others find the sapphire version acceptable for a chronograph. On balance, owners and reviewers rate the Sinn 356 PILOT Classic AS E highly for its vintage aesthetic and strong legibility.

The Echo/Neutra Cristallo Professional Diver 500m is praised for its well-executed 42mm case with polished chamfers and a comfortable H-link bracelet, featuring a functional clasp. Reviewers note its smooth 120-click bezel and a Sellita SW279 movement with power reserve and small seconds complications. One owner flags the inner folding part of the clasp as slightly long. Overall, owners and reviewers rate the Echo/Neutra Cristallo Professional Diver 500m highly for its functional Sellita SW279 movement and well-finished case at its $800 price point.
