Q1: Is this a genuine Bergeon tool?
A: Yes — genuine Bergeon 5499-15 Reversible Stakes, Made in Swiss, brand new in original packing. Original Bergeon tool. Not a replica or generic.
Q2: What are tension rings and why are they important?
A: Tension rings (also called tension gaskets) are the rubber or O-ring seals that create the waterproof seal between the case and case-back, and around the crystal in diver watches. Over time, they compress, harden, or crack — this stakes set allows you to fit new tension rings to restore waterproofing integrity.
Q3: What does reversible mean?
A: Reversible means each stake can be flipped to serve two functions: as an anvil (supporting surface) on one side and as a punch (driving surface) on the other. This dual-function design maximizes the utility of each stake piece in the set.
