A 42 mm Automatic Sports Watch for Daily Wear

The Seiko 5 Sports SRPD71K2 runs on the 4R36 automatic calibre with 24 jewels. A stainless steel case and Hardlex crystal protect the blue dial with dotted markers. It offers 100 m water resistance and a day and date display for everyday utility.

Silicone Strap and Unidirectional Bezel Add

The supplied silicone strap uses a buckle clasp for secure, adjustable fit during activity. The unidirectional bezel allows elapsed-time tracking without accidental rotation. Both elements suit swimming or gym sessions directly from the box.

Verify Wrist Size and Winding Preference Before

The 42.00 mm case diameter and lug-to-lug span determine how the watch sits on smaller wrists. Automatic movement requires regular wrist motion or manual winding to maintain power reserve. Buyers needing a bracelet, sapphire crystal or ISO dive certification should consider other models.

Questions about this item

How often does the automatic 4R36 movement need servicing?

The 4R36 automatic movement typically requires servicing every three to five years to maintain accuracy and lubrication.

What limits daily wear comfort during extended use?

How much heat does the watch generate when worn continuously?
