Pressure testing a Speedmaster.

Omega’s chart showing the water resistance of their watches is interesting.

This Speedmaster is considered safe for a dip in the pool.

We area heading to the beach this weekend so I thought I would take it (Speedmaster sapphire sandwich from around 2007).

First I had to pressure test it.

Set the micrometer to zero - pumped to 2, 4 and 6 Bar.

Maximum crystal deflection was 0.10mm

Left it under pressure for 20 minutes with no change.

I would be confident to take this one to 60 metres but must not wave my hands around at that depth.
