D2™ (010-01040-30)
Garmin
fēnix® Chronos (010-01957-00)
The Garmin D2™ and Garmin fēnix® Chronos share a near-identical 49mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Garmin fēnix® Chronos is the slimmer of the two (15mm vs 17mm), so it slides under a cuff more easily.
On the wrist the Garmin D2™ feels lighter (82g vs 96g, case only).
