What reviewers and owners say
Reviewers
From 4 reviews we read or watched.
Reviewers who handled the PD-1813 like the pale dial, the compact 39.5 mm case and the five-link bracelet with inverted end links, which one says wears shorter than its 48 mm lug to lug suggests. One opened the case back and found a Seiko VK64 mecha-quartz where the brand lists a VK34; the others name a VK34 or give no caliber. One noted that the date is left off although the movement has one. Two found the lume fades quickly and two found the clasp thick or its diver's extension unwelcome. The 20 mm lug width suits strap swaps.
Good
- Compact 39.5 mm case
- Five-link bracelet with inverted end links
- Sapphire crystal with anti-reflective treatment
- 20 mm lug width for easy strap swaps
Less good
- No date, though the movement supports one
- Quartz-based movement and a disputed caliber
- Diver's-extension clasp criticised
- 13.2 mm thick
