SKX007 vs SRPD55
The discontinued SKX007 and the Seiko 5 Sports watch sold as its successor.
The differences that matter
- Size: the SRPD55 is 0.5 mm wider (42.5 vs 42 mm), and 46 vs 46 mm lug to lug.
- Water resistance: 200 m on the SKX007 vs 100 m on the SRPD55.
- Movement: 7S26 in the SKX007 (does not hack or hand-wind), 4R36 in the SRPD55 (hacks and hand-winds).
- Availability: the SKX007 is no longer sold new by Seiko US, so it is mostly bought pre-owned; the SRPD55 is still sold new.
