The short answer: the Söner Amorous (from $620) and the Oris Rectangular (around $2,100) are both Swiss automatic rectangular watches, but they optimise for different things. The Amorous leads on measurable daily-wear specification: an 800HV hardened steel case, 5 ATM water resistance, a 42-hour power reserve, a 10-year warranty and a standard 20mm strap width, all at roughly a third of the Oris's price. The Oris leads on heritage and visible craft: an exhibition caseback, luminous hands, and the identity of a fully independent Swiss manufacture founded in 1904.
Key Takeaways
- Price gap: $620 vs about $2,100, roughly 3.4x, for two Swiss automatic rectangular watches.
- Both use well-regarded Swiss automatics: Söner's Sellita SW100A (25 jewels, 42h reserve) vs the Oris Calibre 561 (based on ETA 2671, 25 jewels, 38h reserve).
- The Amorous leads on measurable specs: 5 ATM vs 3 ATM water resistance, 800HV hardened steel vs standard steel, and a 10-year vs 2-year warranty.
- The Oris leads on heritage and visible craft: an exhibition caseback, luminous hands, and Oris's identity as one of the few fully independent Swiss manufactures.
Two of the most compelling rectangular automatic watches under $2,500 come from very different directions. The Söner Amorous is built by the world's only brand dedicated exclusively to rectangular timepieces, with a specification sheet that punches well above its price. The Oris Rectangular is a heritage Swiss brand applying its independent-watchmaking philosophy to the angular case format it revived in 2021.
This comparison covers every meaningful difference between the two watches: construction, movement, water resistance, wearability, ownership experience, and long-term value.
About the Watches
Söner Amorous
The Amorous is Söner's automatic collection, launched by Swedish founder Freddie Palmgren as the brand's first self-winding line. Söner's entire identity is built around one case geometry: the rectangle. Every design decision, proportion, material specification, and engineering choice is made with rectangular watchmaking as the only reference point, not as an adaptation from a round-case platform.
The Amorous uses the Sellita SW100A, a compact Swiss automatic calibre designed specifically for slim rectangular cases. The case is 40 x 28mm, made from 800HV hardened stainless steel, with a screw-down arched caseback that contours to the wrist. Water resistance is 5 ATM. The warranty is 10 years. Price: approximately $620.
Oris Rectangular
Oris is one of the few remaining fully independent Swiss watch manufacturers, based in Hölstein, Switzerland. The Oris Rectangular was revived in 2021, drawing on the brand's mid-century archive references. It uses the Oris Calibre 561, based on the ETA 2671, a well-regarded Swiss platform with a long service history. The case is 38 x 25.5mm in standard stainless steel. The caseback is a flat see-through design that reveals the movement. Water resistance is 3 ATM. Warranty is 2 years. Price: approximately $2,100.
Who Each Watch Is For
Before going into specifications, understanding the buyer priorities each watch serves makes the comparison clearer.
Choose the Söner Amorous if: you want the best specification-per-dollar in a rectangular automatic, you wear your watch daily and want durability, you value a long warranty as a signal of engineering confidence, and you want a strap ecosystem that works with standard 20mm straps from any supplier.
Choose the Oris Rectangular if: you value established Swiss brand recognition, you want to see the movement through an exhibition caseback, nighttime legibility matters and you want luminous hands and markers, and heritage and collector appeal are part of your decision.
The Söner Amorous emphasises modern materials, higher durability, better water resistance, strap flexibility and a long-term warranty, all at a significantly lower cost. It is engineered for daily wear and offers strong functional value. The Oris Rectangular emphasises heritage, an exhibition caseback, luminous dial elements and established Swiss brand identity. It caters more to collectors who prioritise brand lineage and decorative movement visibility.
Both watches serve different buyer priorities. The Söner is a specification-driven, durability-focused choice with exceptional value. The Oris is a heritage-driven, traditional Swiss option offering visual movement appeal and classic design cues.

Price and Value Positioning
The Söner Amorous is priced at approximately $620, while the Oris sits at approximately $2,100. This places the Oris at more than three times the cost. In the mechanical watch world, price alone does not determine value; buyers weigh the ratio between price, materials, specifications, and long-term support. On that ratio, Söner's cost-to-specification value is significantly higher, while Oris leans on brand heritage, traditional Swiss retail positioning, and the inclusion of collector-friendly features like a see-through case back.
Case Construction and Durability
The Söner uses hardened stainless steel rated to 800HV, which improves scratch resistance and helps the watch keep its finish longer under daily wear. The Oris uses standard stainless steel, durable but more prone to surface marks over time.
There is also a difference in caseback construction. Söner uses an arched, screw-down caseback shaped to contour the wrist for comfort and sealing. Oris uses a flat, see-through caseback that shows the movement but without the same ergonomic curvature. Söner prioritises comfort and durability; Oris prioritises movement visibility.
Water Resistance and Structural Engineering
Rectangular watches are traditionally weaker on water resistance because their geometry makes sealing harder. The Söner reaches 5 ATM, rated for swimming and snorkelling, unusual for a rectangular dress watch and a sign of careful gasket engineering. The Oris is rated 3 ATM, fine for handwashing but not immersion.
Movement Architecture
The Söner uses the Sellita SW100A, a compact automatic movement with 25 jewels, 28,800 vph, and a 42-hour power reserve. The Oris uses the Calibre 561, based on the ETA 2671, also 28,800 vph with 25 jewels and a 38-hour power reserve. The ETA 2671 platform is widely respected for reliability and serviceability, though it is an older design; the SW100A is newer Sellita engineering built specifically for compact rectangular cases. Both movements are well supported for servicing across the industry; the practical difference is power reserve and movement generation.
Crystal, Legibility and Aesthetics
Both models use sapphire crystal with anti-reflective coating, so there is no difference in scratch resistance or glare. The Oris includes luminous hands and markers; the Amorous does not, which gives its dial a cleaner, more dress-focused look but sacrifices low-light legibility. Buyers who read their watch often in dim rooms or at dinner will find the Oris more practical in this one respect.
Strap Compatibility
The Söner uses a 20mm standardised strap width with quick-release spring bars, so third-party straps from any supplier fit without tools. The Oris uses a 19mm quick-release strap, a less common width that limits third-party options and leans buyers toward Oris-branded or custom-cut straps.
Warranty and Long-Term Ownership
The Söner offers a 10-year warranty, unusually long for a mechanical watch at any price. The Oris offers a 2-year warranty, standard within the Swiss industry unless an extended warranty is purchased through an authorised dealer. Söner also includes a unique serial number on each piece; the Oris Rectangular does not, which may matter to collectors focused on resale documentation.
Recognition
Both carry outside validation, in different currencies. Oris's is a century of independent Swiss manufacturing, unaffiliated with any larger corporate group since 1904. Söner's is contemporary and third-party: the design line has won the German Design Award 2026 and an A' Design Award in 2018, the brand is rated 4.93 out of 5 from 524 verified reviews, and it has been featured in The New York Times.
Verdict
These are two genuinely good rectangular automatic watches that answer different questions. The Söner Amorous answers: what is the best rectangular automatic watch for daily wear at a reasonable price? At $620 it is not really competing against watches at its own price point, it is competing against watches at two to three times its price, and winning on specification.
The Oris Rectangular answers: what is the most traditional Swiss rectangular automatic that lets me see the movement and carries established brand heritage? The exhibition caseback, luminous hands, and Oris's independent identity are real advantages for a specific buyer, and the price reflects genuine Swiss manufacturing and heritage.
For most buyers, the Söner Amorous represents the stronger functional value. For buyers who specifically want the exhibition caseback and Oris's independent Swiss identity, the premium is a reasonable trade.

Frequently Asked Questions
Is the Söner Amorous better than the Oris Rectangular?
On specifications, the Söner Amorous outperforms the Oris Rectangular at a fraction of the price: harder steel case, higher water resistance, longer power reserve, longer warranty, and a standardised strap width. The Oris has advantages in brand heritage, luminous hands, and the exhibition caseback. Which is better depends on your priorities.
What movement does the Söner Amorous use?
The Söner Amorous uses the Sellita SW100A, a Swiss automatic movement with 25 jewels, 28,800 beats per hour, and a 42-hour power reserve. It is purpose-built for compact rectangular cases.
What movement does the Oris Rectangular use?
The Oris Rectangular uses the Oris Calibre 561, based on the ETA 2671 platform. It operates at 28,800 vph with 25 jewels and a 38-hour power reserve. The ETA 2671 is a well-regarded and widely serviced movement.
Why is the Söner Amorous so much cheaper than the Oris?
Söner sells direct to consumers without retailer margins, which reduces the final price significantly. Oris distributes through a traditional retail network, which adds cost at each stage. Söner's focus on a single watch category also allows tight supply chain optimisation. The price difference does not reflect a proportional quality gap.
Does the Söner Amorous have lume?
No. The Söner Amorous does not have luminous hands or indices. The dial has a clean, dress-focused aesthetic without lume. The Oris Rectangular does include luminous hands and markers. If low-light legibility matters to you, the Oris has the advantage on this specific point.
What strap width does the Söner Amorous use?
The Söner Amorous uses a 20mm standardised strap width with quick-release spring bars, the most common watch strap width, making it easy to source third-party straps from any supplier without tools. The Oris Rectangular uses a 19mm strap, which limits third-party options.
How does the water resistance compare?
The Söner Amorous is rated to 5 ATM, approved for swimming and snorkelling. The Oris Rectangular is rated to 3 ATM, suitable for everyday splashing and handwashing but not for immersion. For a rectangular dress watch, 5 ATM is unusually high and reflects careful case engineering at Söner.
Is the Oris Rectangular still available new?
Availability has varied; check current retailer stock before assuming new units are readily available, as Oris periodically adjusts its rectangular lineup. Pre-owned and remaining retailer stock are the most reliable way to confirm current pricing and availability.
