He was paired with Ray Gravell, the former Welsh centre, and the two formed a commentary partnership that was attributed as being "instrumental in establishing the channel as a serious rugby broadcaster". Davies travelled to New Zealand in 1983 to commentate on the Lions tour, the first of five Lions tours he covered for S4C. He also covered five Rugby World Cup tournaments, including the inaugural event held in New Zealand and Australia in 1987. During the late 1990s and early 2000s Davies was moved to commentate on games for BBC Wales in the English language. He then was given a choice to remain or return to Welsh language coverage on S4C. He chose the latter, believing that he had more of a contribution to give. Davies made one last appearance as an English language commentator when he took over commentary of the 2013 Wales vs. Italy international match. Having covered the first half in the Welsh language on S4C, he stepped in to cover the second half for BBC Television when the scheduled match commentator, Andrew Cotter, took ill. After covering over 300 international matches, Davies covered his final international in 2014, Wales vs. Scotland. Prior to the game, he was presented with a framed shirt to mark the occasion by Roger Lewis, the chief executive of the Welsh Rugby Union. His final commentary was the 2014 Pro 12 semi-final match held a few months later between Leinster and Ulster. In addition to his sports coverage, Davies also presented Dechrau Canu, Dechrau Canmol. He was also a presenter on BBC Wales's coverage of the annual National Eisteddfod for 33 years, making his debut at the 1980 event held in the Lliw Valley and covering his last in 2012 at the Vale of Glamorgan. In recognition of the contributions made in the Welsh-language, he was honoured as a member of the Gorsedd of the Bards at the National Eisteddfod in 1987 when he was appointed as an Ovate (green robes). Davies adopted Huw Llywelyn as his bardic name. He originally planned to take the name Huw Eic, as a nod to the patronymic naming system that had historically been commonplace in Wales, however his father objected. In 1994, he was promoted to a Druid (white robes). Davies was Chairman of the Working Committee responsible for organising the 2008 National Eisteddfod in Cardiff, which he took on in addition to his presenting duties for S4C.
