Don't know what to get him?
You won't go wrong with these vintage Accurist watch cufflinks. 
Just look at the details in these mechanisms.
Accurist signed their mechanisms in different places and with different fonts so it's really hard to find an exact pair.
Accurist is a British brand which started in 1946 in London. They pride themselves on their mechanisms containing 21 jewels - that's 21 rubies, which act as bearings, making the watch smoother and more accurate. The usual amount in any brand is 15-17.
These cufflinks come to you in a high-quality gift box.
Watch mechanism size 15 x 13 mm
