"The research centre, which published related reports, supports the observation."

As you related it, NO.

Setting off the descriptive phrase, "which published related reports", with commas, as Country Bumpkin has done for you, makes the statement grammatically correct.

The top disc is made of sapphire and has a transparent background showing the hours 1-12 and thus rotating once every 12 hours. You can advance the indicated link hour to quickly track another time zone by pressing the green ceramic pusher located just below the crown link on the case flank. Beneath the sapphire hour disc is a second link disc this time made of brass that manages an indication of daynight by only rotating once every 24 hours. Very clever and rather subtle.
