You mean the classic old Sub? You want a GlideLock clasp to be put on the old model?
...as ThinkBachs said, you can always contact a dealer and buy a bracelet to put on the watch you want, but as far as I know, only Ceramic Subs and DEEPSEA Sea-Dwellers come with GlideLocks (they´re different models tho).
You will need to make the change by yourself tho.
