True if you talk about pure gold. Modern Rolex gold is however only 18K and consists out of 75% gold mixed with 25% alloys of other various metals i.e. a certain percentage of nickel which in turn is much harder than steel.
This is done to create more hardness as a pure gold watch would easily deform. Afterwards temperature annealing for surface hardening as generally for most gold jewellery is applied.
The combination of these two processes makes Rolex gold pretty durable and possibly as hard as steel.
