ZF Factory has released a weighted version of the gold‑toned Daytona, specially designed for buyers concerned that gold‑coloured watches feel too light. As regular readers of our articles know, ZF Factory has solid market channels, yet many of its watches are not manufactured in‑house; instead, they source products from other manufacturers and re‑brand them.

In my personal assessment, its craftsmanship is comparable to mainstream BT Factory and VS Factory offerings, priced slightly lower than Clean Factory. Now that the 4130 and 4131 movements for Daytona are available for bulk order, Daytona replicas have become highly homogenised across brands, even as each factory publishes marketing copy to hype their own products.

Below is the official factory description shared for reference:

1. The 40 mm × 12 mm case is constructed with precious‑metal‑grade material and robust Oyster‑style stainless steel, delivering hand‑feel and hardness identical to the genuine watch. It achieves a total weight of 220 grams for substantial heft. Meanwhile, polishing and finishing on every case detail are finely executed for premium texture.
2. It houses the outstanding 4130 movement. Boasting high reliability and precise chronograph functions, this ingeniously engineered movement uses a reduced number of components, lowering mechanical complexity while boosting stability and durability. It delivers approximately 72‑hour power reserve for daily wear. Rigorously calibrated, it maintains excellent time‑keeping accuracy.
