Don't worry about posting your Seiko to us, as we have never lost a watch.
This is because we only use Royal Mail "Special Delivery" also "Special Delivery" is the only one that insures Jewellery.

If you take your Seiko to a High Street Jewellers they will not repair it.
Normally they will post it to Seiko by none insured "Recorded Delivery" unless you pay extra for "Special Delivery".

Also Seiko will return it by "Recorded Delivery" unless you pay extra for "Special Delivery".
