Seiko expanded their popular Sharp Edge family earlier this year with the release of an open heart design in the reference SPB415 and SPB417. The Sharp Edge is a series we’ve been curious about since it was first introduced in 2020, and this latest release has finally given us a chance to go hands-on. Our full review on this watch (from our Ed Jelley) is coming soon, but we took the opportunity to get a quick first reaction when the watch landed in our office, and it wasn’t without a few surprises. Chief among them is that dial texture, which hits very differently than the press images.
Open heart dials are a bit polarizing, but Seiko takes an interesting approach here with the design of the section over the aperture. It feels elevated somehow. The dial is downright perplexing, taking on a different personality at varying angles and lighting situations. But in use, the case itself presents what might be the most compelling feature here, with large geometric surfaces and a mixture of finishes breathing life into the ergonomic profile. How that stands up to further scrutiny remains to be seen.
