- Status
- Discontinued. Availability re-check (2026-09-19): the maker's own dedicated page for SMB511, under both the old collection path (SHARKMASTERBRONZEautomatic) and the current one (SHARKMASTERBRONZE44mmautomatic), returns a CodeIgniter "Trying to get property of non-object" error, meaning the product record itself is gone from the store's database. This is NOT a whole-brand failure: oceanx.com's other Sharkmaster Bronze pages load cleanly (SMB541 Onyx Stone renders fine at $1,198), and the site's live nav for that line now lists only SMB541 to SMB544, a stone-dial limited-edition series that replaced the plain SMB511. The retailer citation (Serious Watches) still resolves but its own schema.org markup reads availability OutOfStock. Archived rather than filed as a defunct brand, since the maker's store is demonstrably alive.
