All Filippo Loreti watches are water-resistant (waterproof). You can check the exact water-resistance for your model here.
The water-resistance of a Filippo Loreti Muse collection timepieces is 3ATM (30m), which means it is rain/splash resistant but should not be exposed directly to water.
The Venice Moonphase, Venice Automatic, Rome, Rome Automatic, Essence, Marble, Genoa, Renaissance, Milano, Milano Automatic and Florence watches have a water resistance of 5ATM (50m) and can withstand a brief submersion underwater (i.e. hand washing). We recommend taking off your watch before showering, bathing, swimming, or engaging in any activity that may involve prolonged exposure to water.
Okeanos, Ascari, Chronus timepieces have a 10ATM (100m) rating and can be used while swimming at the surface or snorkeling at a shallow depth, but cannot be used when scuba diving.
Okeanos Automatic models have a 20ATM (200m) which is suitable for all high impact water sports and scuba diving at depths not requiring helium gas.
Here is a chart to show a water resistance rating for the watches:
