I have many IWC watches (all are Porsche Design Ocean 2000 or Ocean Bund watches) but I've never tried getting them serviced at an IWC Boutique. I did send an email to the IWC Boutique in New York City via their website asking if they still sell the Velcro straps for the Ocean models. I received a polite email response that these parts are no longer in stock, but then they recommended I check with a 3rd-party IWC authorized repair shop in New York City (who are well known in collector circles to service the Oceans). I consider that a positive experience.
