Rolex GMT and GMT-II have been made with both Oyster and Jubilee links. Older models use a hollow center-link while newer models feature a solid center link. Note that the newest style 15.5mm Jubilee link is not interchangeable with a Datejust 41mm Jubilee link. Both are 15.5mm but the screw diameter is different. We carry all versions, including steel, two-tone, and solid gold.
