Owners praise the Core Timepieces Original Sin's dial design, noting the chapter ring's functionality negates the need for applied indices. One owner finds the titanium V2 model overpriced at $800 given its NH35 movement, with others questioning its market appeal. Some users express concerns about quality control and reliability, while others prefer its accuracy and style over competing brands. Overall, owners rate the Core Timepieces Original Sin highly for its functional dial design and accuracy, despite some concerns regarding value and reliability.
