What makes the dial and bracelet distinctive?
The gold-treated rippled dial
Venezianico describes the dial as a multi-step process: the disc is tumbled to create its rippled surface, polished in preparation for the gold layer, and immersed in an electrolytic solution containing pure 24-karat gold particles for galvanic deposition. The brand says the dial is then inspected. This is the manufacturer’s account; the page does not give a measured coating thickness or independent durability results.

- Case Material: Robust 316L Stainless Steel
- Dial: Luxurious 24k Gold Treatment with Rippled Finish
- Size: 42mm, Lug to Lug 49mm
- Movement: Precision Swiss Made Cal. Sellita SW200-1 Automatic
- Crystal: Durable Sapphire with Anti-Reflective Coating
The Sansovino bracelet
According to Venezianico, the five-link Sansovino bracelet has two polished links and three satin-finished links, plus a solid clasp with micro-adjustment. The brand says its design takes inspiration from Renaissance sculptor Jacopo Sansovino; that is a design attribution from the manufacturer.
How does the 42 mm compare with the 39 mm?
The smaller Nereide Aureo 39, reference 3121590S, keeps the gold-treated rippled dial and much of the listed construction, but changes the case dimensions and movement. Here are the documented differences and shared specifications:
Rank #2
- Case Material: 316L Stainless Steel
- Dial: Mother of Pearl
- Dimensions: 39mm, Lug to Lug 45.5mm
- Thickness: 10.5mm
- Movement: Automatic Miyota 9039
| Feature | Nereide Aureo 42 (4521590S) | Nereide Aureo 39 (3121590S) |
|---|---|---|
| Case diameter | 42 mm | 39 mm |
| Lug-to-lug | 49 mm | 45.5 mm |
| Thickness | 12.5 mm | 10.5 mm |
| Movement | Sellita SW200-1 automatic | Miyota 9039 automatic |
| Date display | Yes | No |
| Listed water resistance | 200 m | 200 m |
| Official-page price accessed October 8, 2026 | €1,295 sale price | €900 |
The prices are what the respective Venezianico product pages displayed when accessed on October 8, 2026; they may change. The brand lists both models with a 316L steel case, sapphire crystal with anti-reflective coating, tungsten bezel, BGW9 lume and 200 m water-resistance rating. See the official 42 mm and 39 mm pages for their current specifications and prices.
The practical choice is chiefly about dimensions and the date: the 42 mm is larger and thicker, with a date-equipped Sellita; the 39 mm is smaller and thinner, with a date-free Miyota. The available product information does not establish which movement is more accurate, reliable or serviceable.

Rank #3
- Casing Material: 316L Stainless Steel
- Size: 39mm, Lug to Lug 45.5mm
- Movement: Automatic Seiko NH34A GMT
- Features: GMT, Date Display
- Crystal: Sapphire with Anti-Reflective Coating
What do the water-resistance rating and sales terms establish?
Venezianico lists the 42 mm watch at 20 ATM / 200 m / 656 ft and describes it as water-resistant to 200 meters. That manufacturer rating is not evidence here of independent dive testing or suitability for every kind of diving. The product page also gives a two-year international warranty through the brand’s website and authorized retailers and a 14-day return window. Warranty and return conditions can depend on jurisdiction and may change, so confirm the applicable terms before purchase.
The brand connects the model name to the Nereide submarine, calling it “a marvel of Venetian naval technology.” That is promotional language on the product page, not independent historical verification.
Rank #4
- Case Dimensions: 39 mm, Lug to Lug 45.5 mm, Total Thickness 13.4 mm
- Movement: Automatic Seiko NH34A GMT
- Case Material: 316L Stainless Steel
- Crystal Insert: BK7, Polished, Durable, High Optical Clarity, Low Dispersion (Abbe 60)
- Dial: Brass with Sunray Finish
What has not been independently established?
The cited product information is primarily Venezianico’s own copy and specifications. It does not provide independent performance tests, accuracy results, or long-term wear evidence for the Nereide Aureo 42. The listed movement, materials and ratings can explain what the manufacturer says it is selling, but they should not be mistaken for third-party verification of real-world performance.
