Due to smartwatches’ usual strong functional dependence on other devices from the same manufacturer, we believe that Past Product Expectation Confirmation—which we describe as the extent to which a person believes that his/her expectations were satisfied by a specific manufacturer’s product portfolio in the past—influence people’s usage of smartwatches. After collecting 229 completed online questionnaires about the Apple Watch, and applying a structural equation modeling approach, our findings indicate that smartwatch usage is positively influenced by Perceived Usefulness. Past Product Expectation Confirmation was found to have a direct positive influence on the Behavioral Intention to Use smartwatches as well as an indirect positive influence on the Behavioral Intention to use smartwatches through Perceived Usefulness. These findings emphasize the importance of having strong product portfolios so that manufacturers can launch equally successful products in the future.

... Some of the most utilised theoretical models to examine smartwatch user behaviour are the Technology Acceptance Model (TAM) Chuah et al., 2016;Dutot et al., 2019;Kim & Shin, 2015;Nasir & Yurder, 2015;Niknejad et al., 2020), Unified Theory of Acceptance and Use of Technology (UTAUT) (Dehghani, 2016;Gu et al., 2016;Rubin & Ophoff, 2018), Expectation Conformation Theory (Bölen, 2020;Ernst & Ernst, 2016;Pal et al., 2018), and Innovation Diffusion Theory (Dehghani, 2018;Hong et al., 2017). A comprehensive literature review by Niknejad et al., (2020) shows that, unequivocally, TAM is the adoption model of choice to examine user behaviour with 25 articles, followed by DOI (diffusion of Innovation) and UTAUT with 12 and 11 articles respectively. ...
