Noticed with 0.15 (although it exists as at least as far back as 0.12) that the digital clock watchface is first populated with placeholder text / icons, and then the final display set, when returning to it from the menu (not from sleep). It became more obvious with the 0.15 version as there is a flash of colour up the top as the charge and bluetooth icons appear and disappear (they disappear to reflect the true state of the device).
