A question to all of you who have been using a F3HR, F5 or F5plus.
During the cold period of the year I normally wear my watch on the outside of my clothes, no problem since it is (was) a F3. I recently switched to a F6X Sapphire and I'm a bit concerned about the OHR sensor, is it durable enough to wear outside the clothes for about 3-5 activities a week?
Best regards,
Tobias
