The clock is really nice! But unfortunately it was defective upon delivery. She stopped again and again by new time setting, are after about 15min. Good things can happen, nothing is infallible! The communcation to run a Italian supplier, 2S Time with which the conversation is run in English and without any complaint. Something impractical proved for me to replace the battery, I have made at the initiative of 2S Time, in hopes of then problem-free operation. One has to find a dealer who has the ability to test for battery change the clock again to 10bar, otherwise it is possible where not very close. That was not so easy. Well everything else good, money back and good! And another Seiko ordered without the Batteriewechselact! ;-)
