Omega
Seamaster Aqua Terra 150M
The 38mm Aqua Terra in blue is, genuinely, one of the most wearable watches Omega makes and I will die on this hill. The teak-pattern dial catches light in this subtle, shifting way that rewards you throughout the day - you glance down at 2pm and it looks completely different than it did at 9am. Cal. 8800 is a workhorse in the best sense: Co-Axial escapement, Master Chronometer certified, and it handles magnets better than almost anything else at this price. At 38mm it fits under a shirt cuff without drama. Goes with everything. This is my 'buy it, wear it, never think about it again (in a good way)' recommendation. It's just a really, really good watch.
