Construction and Materials

The 42mm case and bezel are machined from 904L stainless steel, a high-grade alloy known for superior corrosion resistance and a brighter polish than standard 316L. The black dial features applied stick indices and hands in matching 904L steel. Sapphire crystal protects the face from scratches, while the solid case back and precise finishing mirror the original Moonwatch profile.

Physical Specifications and Testing

Measuring 14.00mm thick with a 42mm diameter, this Speedmaster Professional 145.022-69 ST replica passes a 30m water resistance test at 3 ATM. The automatic caliber 861 delivers a 60-hour power reserve and -3/+3 sec/day precision within COSC limits. The adjustable steel bracelet fits all wrist sizes with a fold clasp. Note: swimming is not recommended despite the water test.

Real-World Wear Experience

On the wrist, the 42mm case sits comfortably under a shirt cuff for office days, while the tachymeter bezel and chronograph function prove useful for timing commutes or workouts. The sweep second hand and flyback function add a tactile engagement that quartz alternatives lack. For collectors seeking a complementary piece, the Apollo 8 chronograph black ceramic offers a darker, modern alternative within the same Speedmaster family.

Purchase Considerations and Care

Before buying, confirm the 30m water resistance is suitable for accidental splashes only—avoid swimming or showering. The sapphire crystal resists scratches but should be cleaned with a soft cloth. This watch comes with a full 2-year International United Luxury warranty covering mechanism issues. Serial numbers and cards are arrangeable, and the font and finishing match the authentic reference.

Design Value and Daily Use

The black dial with stick markers provides high legibility in low light, while the 904L steel bracelet balances heft and comfort for all-day wear. The chronograph and tachymeter functions add practical utility for timing events, and the 60-hour power reserve means the watch keeps running through a weekend off the wrist. It is a faithful homage to the Apollo XI Moonwatch legacy.

Specifications & Care:

How should I clean my Speedmaster clone?

Use a soft, dry microfiber cloth to wipe the case and crystal. Avoid chemicals or abrasive materials. For a complementary piece, consider the Planet Ocean 600M black dial which shares similar care needs.

Can I swim with this watch?

No, despite passing a 30m water resistance test, swimming is not recommended. It is suitable for accidental splashes only.

How often should I service the movement?

We recommend servicing every 3-5 years to maintain precision and power reserve, similar to genuine automatic watches.

What is the power reserve and how do I maintain it?

The 60-hour reserve means you can take it off for a weekend. Wind it 20-30 turns if it stops, or wear it daily to keep it wound.

Does the chronograph affect water resistance?

Do not operate the chronograph pushers underwater or when wet, as this may compromise the seals.
