@RafaelBernard its an LSATMax watch but an older model without the rotating bezel. It has a crown that you can use to pause and reset the timer so I'm a bit surprised that this watch got approved.
@akistotle I'm thinking of bring both just in case. Having a rotating bezel might be more convenient since it takes longer to pull and the push down crown to reset the time as opposed to just rotating a bezel.
