We recommend having an expert check the water-tightness of every Habring² once per year. The test usually only takes a few seconds and can provides information on the condition of the seals. It also gives the watchmaker an opportunity to check internal components for any signs of wear. Indications of wear signal the need for a general inspection, which is usually due every five years.

The rubber seals (bezel, base and crown/button seals) that protect the movement against water penetration may need to be replaced more frequently to guarantee water-tightness.
