Apple Watch Ultra has dual frequency:

"The Apple Watch series has always offered GPS support (in addition to other global satellite navigation systems), but the Apple Watch Ultra is the first to come with dual-band GPS (L1 + L5). Most smartwatches on the market, including the Galaxy Watch 5, only support single-frequency GPS and can only receive satellite signals on the L1 frequency. Dual-frequency support allows the Apple Watch Ultra to lock onto L1 and L5 bands simultaneously. This greatly improves navigational positional accuracy and reduces multipath errors in urban areas and other challenging environments."
