Luxury sports products and brands in general have seen a significant increase in their sales, highlighting the high consumption of smart sports watches. The purpose of this study is to investigate the mediating role of cobranding, self-presentation, self-expression, and symbolic values in the relationship between the consumer’s need for uniqueness and the intention to repurchase luxury smart sports watches. The sample consisted of a total of 217 users of smart sports watches. An online questionnaire was used for data collection (24 items from 6 scales) and Smart PLS-SEM software was used for confirmatory factor analysis and to test a structural equation model. The findings provide an insight into the importance of cobranding on self-expression, self-presentation, and symbolic value. Specifically, in the case of intention to repurchase, the results show that symbolic value is the variable with the highest predictive value. This study provides an important advance in the academic literature related to luxury products in the sports sector, and the results facilitate a better understanding of the consumer’s intention to repurchase.
