Seiko 5 Sports Field Blue Dial Automatic SRPG29 SRPG29K1 SRPG29K 100M Men's Watch Inspired by vintage field/military style watches, this automatic watch comes with manual winding capability. It runs for more than a day and a half on a fully wound mainspring; when you wear it on a regular basis (every alternate day), the red-orange tipped seconds-hand never stops moving. Best if winded fully manually before first use. For best results, never allow the watch to stop.
