Watch maybe not showing minutes produces row (4)
I believe the answer is:
tier
'row' is the definition.
(tier is a kind of row)
'watch maybe not showing minutes' is the wordplay.
'watch maybe' becomes 'timer'.
'not showing' suggests deleting specific letters.
'minutes' becomes 'm'.
'timer' with 'm' taken out is 'TIER'.
'produces' is the link.
(Other definitions for tier that I've seen before include "Level - layer" , "Rite (anag.)" , "One of two or more rows" , "Plague" , "Person joining" .)
