Speaking about the partnership, Connacht Rugby's commercial manager Fiona Keys said: "We are thrilled Hartmanns of Galway will be sponsoring our Player of the Month award with such an exclusive prize.
"As the leading jewellers in the West of Ireland, Hartmanns of Galway are synonymous with integrity, value, quality and service and we see these characteristics as a very close fit with our own."
Connacht head coach Eric Elwood added: "The Player of the Month award is highly sought after within the squad as it reflects not just the hard work the guys do on the pitch but the contribution they make off the field as well.
"Having a family-owned business with a reputation such as Hartmanns of Galway sponsoring the award, with a Tag Heuer watch, adds incredible value to the honour and we are delighted with the partnership."
Fourth generation director Richard Hartmann commented: "Hartmanns of Galway are very excited about this partnership; it provides us with a unique and innovative way to interact with the Connacht Rugby and align both brands.
"Tag Heuer are the official timekeepers or the Rugby World Cup and it is very fitting that we can offer this exclusive prize to the Connacht Player of the Month."
The first recipient of the Connacht Player of the Month award is second row Michael Swift. After earning over 200 caps for Connacht, the 33-year-old is very much an integral member of the squad.
'Swifty' is heavily involved with as many aspects of the province off the field as he is on the pitch. He was presented with his Tag Heuer watch, for being the Player of the Month for September, by Richard Hartmann at their Shop Street premises.
Hartmanns of Galway are the only store in the West of Ireland where you will find top Swiss watches such as Rolex, Tag Heuer and Omega.
They are exclusive agents for designer jewellery brands such as Hearts on Fire, Marco Bicego and Fope. They are also stockists of top silver brands Ti Sento and Links of London.
Beyond this array of premier designers and watch brands, you will find the most exclusive collection of diamond engagement and wedding rings and their team will be delighted to present to you in the comfort of their private viewing rooms.
