[VIDEO] First-Look at the Seiko Presage Sharp Edge SPB417

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.


This watch may not have fully won me over on the open heart concept, but it has made me quite keen on the Sharp Edge collection as a whole. Stay tuned for the full review coming later this week to for Ed’s feelings. Seiko.
