I have lost the small rubber dust cover that covers the charging port on my Polar M400 watch and would like to purchase a new one. Are they available?
Huw, later versions of the M400 removed the dust cover as it hindered the drying out of the charging port, so I don’t think you need to replace it. The charging port is problematic and mine has now broken. The newer model M430 has a more robust charging port.
