For those in Singapore, I just want to let you know that JW Horological Gallery now offers sand blasting service.
Their website states that the service is provided for Fortis, IWC, Laco, Glycine, Sinn and others. If ‘others’ includes Seiko divers, then it would be easier to modify Seiko divers in Singapore. So rush down to Cash Converters to hunt for used SKX divers now.
