Master Clone Level — Precision Across Every Detail

The 1:1 Master Clone designation means every measurable dimension has been verified against the genuine reference.

A watch built for collectors who know the genuine reference and will hold this superclone to the same standard.

Frequently Asked Questions

Can the GMT hand be set independently of the hour hand?

Yes. The clone movement supports independent GMT hand setting — pull the crown to the second position and rotate to advance the GMT hand in one-hour increments, independently of the main hour hand. This allows you to track a second time zone without disrupting your local time display.

Is the date complication present on the Explorer II?

Yes. The 216570 has a date window at 3 o'clock with a Cyclops magnifier on the sapphire crystal, consistent with the genuine reference.

Why does the Explorer II use a fixed bezel instead of a rotating one?

The fixed 24-hour bezel allows you to read the time of day (AM vs PM) directly from the 24-hour hand position against the bezel scale, without the risk of the bezel being accidentally rotated and losing the calibration. It is a more reliable time-zone reference than a rotating bezel for this function.

What lug width does the Explorer II use?

The 216570 uses a 21mm lug width — slightly wider than most Oyster sports models to complement the 42mm case diameter. The Oyster bracelet fitted to this superclone is the correct 21mm width.

Has the Explorer II always had an orange GMT hand?

The orange GMT hand was a feature of the original 1971 Explorer II. It was maintained through subsequent generations as the reference's most distinctive visual signature. The 216570 carries on this tradition.
