Seiko SRPE17J1 vs Seiko 5 SNKK71K1

The SRPE17J1 is the better watch of the two. It has a modern 4R35 movement with hacking and hand-winding, a box-shaped Hardlex crystal, a 40.5mm case and a push-button deployment clasp. The SNKK71K1 is a smaller, older Seiko 5 with the 7S26 movement, which cannot be hand-wound or hacked, and only 30m of water resistance. Owners praise the SNKK71K1's compact 38mm case and sunburst dial, but most find the SRPE17J1 the stronger everyday watch.

• Choose the Seiko SRPE17J1 if you want a larger, more modern automatic with hand-winding, hacking and a crystal that resists scratches better.
• Choose the Seiko 5 SNKK71K1 if you have a smaller wrist and prefer a compact 38mm case with a sunburst dial and day-date.
