3. Orient Polaris GMT
Orient consistently delivers incredible value for money, and the Polaris is no exception. You get an automatic movement powering an independatly-adjustable GMT hand, power reserve indicator and date function, all housed in an elegant, white-dialed 42mm case with blue steeled hands for $415.
4. Luminox RECON Nav SPC-8832.MI
A 46mm case may be large, but Luminox fit a ton of watch in here: you get a 24-hour bezel, a tachymeter scale in miles, an alarm function, a GMT function, 200m of water resistance, a countdown quadrant, and a black rubber strap with raised scale and compass. To want anything more for $500 would be a heavy ask.
