For most buyers, the best Omega 3520 replica is a top-tier Speedmaster Day-Date 3520.50.00 with a working Asian 7751 clone, a 39mm stainless steel case, and a sapphire crystal. It delivers the full day-date-month calendar, 24-hour subdial, and chronograph functions that define the original. If you want the closest look and feel without paying vintage genuine prices, this is the version to pick first.

What the Omega 3520 Replica Should Get Right
The Omega 3520 is shorthand for the Speedmaster Day-Date reference 3520.50.00. The genuine watch uses the Omega calibre 1151, a self-winding chronograph with day, date, month, and 24-hour displays. A good replica must match the 39mm case, the black dial layout, the three subdials, and the pusher positions. Many cheap versions fail here: they use a quartz movement with fake subdials or a 7750 base that lacks the month and 24-hour functions.
Best Pick: Top-Tier 7751 Clone
This is the option to choose if you care about function and feel. It uses an Asian 7751 automatic movement, which is a clone of the Valjoux 7751. The day, date, month, 24-hour, and chronograph all work. The case is 39mm, the crystal is sapphire, and the dial printing is close to the original. The bracelet should have solid links and a proper clasp. The main trade-off is price and servicing. A 7751 clone can be less reliable than a simple 7750, so buy from a seller who offers a warranty.
Mid-Tier Option: 7750 With Faux Calendar
Mid-tier Omega 3520 replicas often use a 7750 chronograph movement. The chronograph works, but the day, date, month, and 24-hour subdials may be decorative or only partially functional. This option can look good on the wrist, especially if the dial and case are well finished. It costs less than the top-tier 7751 version. If you rarely use the calendar functions, it can be a reasonable compromise. But a replica review should be honest: the lack of working calendar functions is the biggest giveaway to anyone who knows the model.
Budget Option: Quartz
Budget Omega 3520 replicas often run on quartz. They keep time accurately and cost the least. However, the seconds hand often ticks instead of sweeping, and the subdials are frozen or fake. The case finishing is thinner, and the crystal may be mineral glass. This option is best for a costume piece or a test of whether you like the 3520 design. It is not the best choice if you want a convincing Speedmaster Day-Date replica.
How to Compare Omega 3520 Replica Versions
- Movement: Look for a 7751 clone with working day, date, month, and 24-hour. Avoid quartz if you want a sweeping seconds hand.
- Case size: The original 3520.50.00 is about 39mm. A replica that is 42mm or larger will wear differently.
- Dial: Check subdial positions and font. The date and month windows should be crisp, not painted on.
- Crystal: Sapphire is preferred for scratch resistance. Mineral glass is common on budget models.
- Bracelet: Solid links and a signed clasp feel better and last longer.
- Water resistance: Most replicas are not made for swimming. Do not trust a high rating without a pressure test.
Final Verdict
The top-tier 7751 clone is the best Omega 3520 replica for most buyers. It offers the full function set and the closest visual match to the Speedmaster Day-Date 3520.50.00. The mid-tier 7750 version is a budget-friendly compromise if you can accept faux calendar subdials. The quartz version is only for casual wear. Before you buy, ask the seller for real photos, a video of the functions, and a return policy. That simple step separates a good replica review from a risky purchase.
