Status
Current (between batches). Thorn uses the model code SHY037 for two functionally different watches sharing the same 40.5mm x 48mm x 14mm titanium case: this three-hand NH35 automatic diver with a plain lume-dot ceramic bezel and no date or GMT, and a separate NH34A GMT / helium-valve version already catalogued as thorn-shy037-helium-gmt-titanium-ti. The two are independently confirmed on the maker's own storefront and its Heimdallr storefront mirror, both stating NH35 with no GMT function, against the other record's citation which independently states NH34A Automatic GMT with date and dual time zone.
