Norwich-based independent jeweller Winsor Bishop is on target to achieve the highest sales growth in its 185-year history, Jewellery Focus can reveal.\r\n\r\n\r\n\r\nIn the financial year to date (from 1 April to 31 December), the jeweller - which was victim of an armed robbery earlier this year - reported a total sales increase of 24%, with footfall and web traffic up 20% and 61% respectively for December alone, when compared with the previous year.\r\n\r\nThe company said that the hike in sales was driven by greater new watch sales, particularly Patek Philippe and Rolex, along with an uplift in diamond sales, both in terms of unit sales and average transaction values.\r\n\r\nThe growth in diamond sales was encouraged by \u201csignificant\u201d growth in both diamond rings and diamond jewellery, which saw growth of 30% and 20%, respectively.\r\n\r\nThe firm said that it had a \u201cvery clear\u201d strategy for 2015, and that channeling different methods has helped to deliver \u201cexcellent\u201d results.\r\n\r\nSpeaking to Jewellery Focus, managing director Sophie Fulford said that in the company\u2019s first two financial quarters it was running about 26% ahead of the previous year, before hitting a \u201cbrick wall\u201d in the first six weeks of the Christmas trading period.\r\n\r\nShe added: \u201cOur trading patterns then changed and we had three peaks. Black Friday, eight trading days before Christmas eve and Boxing Day saw trading change significantly. Boxing Day sales were brilliant and the best we\u2019ve ever done - we finish that next week so it\u2019s still ringing through.\u201d\r\n\r\n\u201cWe\u2019re not looking at significant growth this year for Winsor Bishop, we have some other projects in the pipeline. We will be looking at some more efficient ways to do things and we now have much more clarity on what trigger dates are important in the calendar year.\u201d\r\n\r\nMeanwhile, Winsor Bishop - a member of The Houlden Group's Jewellers of Excellence - also opened the doors of its first franchise store with Swarovski in October 2015. \r\n\r\nThe company said the Norwich-based store had an \u201cexcellent first quarter\u201d, already performing above target.
