a few here = baby g’s
I have small wrists and have 2 baby shocks which are perfect. Have a look for neutrally coloured ones – look perfect on men and women. Just replaced the battery on one of them after a number of years. Cost £1.80. with the right mini watch screw driver and a little help from amazon. Great watches imo although it out’s of warranty and old now.
Bottom blue one has a smaller face than the upper ones and are not quite as good technically but are still brilliant and well priced. Think it is exclusive to Argos but may be wrong.
The top ones are often down to £40 so may be worth using amazon or waiting a while. Have a good scroll through Amazon as there was loads of unisex looking ones well within your budget.
