Seiko & Citizen Watch Forum Message Archive

I realise the Seikos are sealed to only allow a minimum of helium to enter.

My question is would the amount of helium entering the watch be cumulative over many dives?

Or would the helium automatically start leaving the watch at sea level?

Although if difficult to get in I guess it is difficult to get out?

If the amount was only negligible it could be vented on surfacing anyway IMO by opening the crown.

Cheers,

Neil.
