In-Depth Comparison

The PD-1645 line is a Datejust-inspired watch popular for its high-end features (sapphire crystal, 100m water resistance) at an entry-level price. The V3 designation indicates a continuous effort by Pagani Design to improve the overall quality of the product.

1. Performance and Movement

Both versions are designed to use a reliable Japanese automatic movement.

• PAGANI DESIGN PD-1645 V3: This version is consistently advertised with the Seiko Instruments NH35 automatic movement. The NH35 is a reliable workhorse movement that features hacking (the second hand stops when the crown is pulled out for precise time setting) and hand-winding (you can wind the watch via the crown). The V3 is marketed as having an "enhanced movement", which can imply better regulation (accuracy tuning) than previous batches.
• PAGANI DESIGN PD-1645 (Base): While many base models also use the NH35, some older or specific batches of the PD-1645 may have utilized the Miyota 8215 movement. The key difference is that the Miyota 8215 does not hack, and it is known for a slight 'stutter' in the second hand sweep due to its indirect drive system.

VERDICT: The V3 offers more certainty of receiving the superior and more consistent Seiko NH35 movement.

2. Build Quality and Finishing (The Main Upgrade)

The "V3" primarily focuses on addressing minor flaws found in earlier iterations.

• PAGANI DESIGN PD-1645 V3: This version is advertised with "premium finishing" and is the "upgraded V3 model". This typically translates to:
  • Tighter Tolerances: Reduced gaps between the case and the bracelet end links.
  • Improved Bracelet and Clasp: Later PD-1645 models (which the V3 is the newest iteration of) have been noted for having an improved clasp design, potentially including a milled flip-lock and a Rolex Easylink-style 5mm extension for on-the-fly micro-adjustments.
  • Refined Case Details: One user noted a change in the crown guard between the V2 and V3, suggesting subtle case refinements are part of the upgrade path.
• PAGANI DESIGN PD-1645 (Base): While still excellent value, earlier versions often received criticism for minor quality control issues, such as looser bracelet links, slightly sharper edges on the clasp, or less consistent finishing on the fluted bezel.

VERDICT: The V3 is a safer bet for a higher-quality feel, especially in the bracelet and overall case finishing.

3. Aesthetics and Features

In terms of core aesthetic, both watches are nearly identical: a classic, 42mm Datejust homage with a fluted bezel, cyclops magnifier over the date window, and a Jubilee-style or Oyster-style stainless steel bracelet.

• Lume: Both versions use a green C3 Lume, which provides adequate performance for the price point but may not be as bright or long-lasting as higher-tier Super-LumiNova.
• Crystal: Both feature Sapphire Crystal (with a cyclops magnifier), which is a huge value proposition at this price point, offering superior scratch resistance over mineral glass.
• Water Resistance: Both offer a reliable 100m (10 Bar) water resistance with a screw-down crown, making them suitable for swimming, snorkeling, and daily wear.
