Broken clasp on my Seamaster Aqua Terra

I have owned my Seamaster Aqua Terra for about 10 years. I wear it every day and it is serviced regularly. Recently the clasp on the 1574/898 bracelet has broken. The piece which contains the spring clasp has broken off.
I do not want to buy a whole new bracelet as it appears the one link which houses the clasp is replaceable.
I would welcome any advice on whether this is a possibility. My trusted jeweler is obviously closed at the moment but I want to have the info' ready for when he opens the door again.
Thanks in advance for your guidance.
