Abstract: Watson and Whipple (1925) discovered two summation formulae for a $ _3F_2(1)$-series. Their terminating $ q$-analogues were found by Andrews (1976) and Jain (1981). As a common extension of these results, we prove a general bilateral series identity, which may also be considered as a full $ q$-analogue of the $ _3H_3$-series identity due to M. Jackson (1949). This will be accomplished by means of the modified Abel lemma on summation by parts.
