Just like its cousins, these watches come in both the 38mm and 41mm case sizes, and all the specs from the Aqua Terra line remain the same. Both sizes are water resistant to 150m, and the 38mm case has a thickness of 12.4mm, while the 41mm case is 13.3mm tall. The in-house 8800 caliber powers the 38mm, while the larger variant gets the 8900. Each of these calibers, like many in Omega’s catalog, is METAS certified as a Master Chronometer and able to withstand magnetic fields up to 15,000 Gauss.
