The Rolex 62510H and 62523H are early-generation Jubilee bracelets featuring 20 mm end links and hollow center links. These bracelets were widely used from the 1960s through the 1980s on popular models such as the Rolex Datejust 1600-series and two-tone Datejusts.
They share the same 5-piece link Jubilee construction but differ in material composition:
62510H = All stainless steel
62523H = Two-tone Rolesor (stainless steel outer links + 18k yellow gold hollow center links)
