Frequently Asked Questions
What is the difference between the automatic and quartz Thunderbird?
The Thunderbird 8N24 automatic is a 3-hand self-winding skeleton watch — no chronograph. The Thunderbird 0S00 quartz is a chronograph with stopwatch sub-dials. Both share the same case, sapphire crystal, and 100m WR.
Does the Thunderbird automatic have a chronograph?
No. The Thunderbird Miyota 8N24 automatic is a 3-hand watch — hours, minutes, and seconds only. It does not have a chronograph or stopwatch complication. The skeleton dial exposes the automatic movement's mechanics. Only the Thunderbird 0S00 quartz has a chronograph function with pushers and sub-dials for elapsed time tracking.
What does a chronograph function do on the Thunderbird quartz?
The Thunderbird 0S00 quartz chronograph features a stopwatch function operated by two pushers. The upper pusher at 2 o'clock starts and stops the elapsed seconds hand. The lower pusher at 4 o'clock resets. Sub-dials track cumulative elapsed minutes and hours. On a pilot watch, this is used to calculate approach time, fuel burn intervals, or holding pattern duration.
Is the Thunderbird skeleton watch automatic or quartz?
The Thunderbird skeleton is automatic, powered by the Miyota 8N24 self-winding movement. The open-worked skeleton dial exposes the movement's gears, bridges, and balance wheel. It requires no battery and winds itself from wrist motion. The skeleton configuration is not available in quartz — the open-worked dial design is exclusive to the automatic variant.
Which Thunderbird should I choose: automatic skeleton or quartz chronograph?
Choose the Thunderbird 8N24 automatic skeleton if you want a mechanical watch with visible movement and no need for a stopwatch function. Choose the Thunderbird 0S00 quartz chronograph if you need elapsed time tracking via pushers and sub-dials, and prefer the low-maintenance precision of quartz. Both are built to the same standard: sapphire crystal, PVD steel, 100m water resistance, free shipping.
