Its appeal rests on wearable proportions and unusual dial colors rather than extra functions. The published specifications make it worth considering if you want a smaller, lightweight-feeling sports watch, but current price, stock and regional availability are not established here.
What is the J&Berg B2?
The B2 is a time-only watch from J&Berg. Fratello’s 2025 article presents it in Lake Blue and Misty Green and describes those versions as non-limited editions. The same article is identified as a partnership post, so its positive evaluative language should be read in that editorial context; it is not an independent test report.
Fratello’s 2024 hands-on coverage discussed an earlier set of dial colors: turquoise, copper and dark brown. That first batch was reported at 50 watches per color. These are distinct launches, not evidence that all colorways are currently available.
J&Berg B2 specifications
| Specification | Published details |
|---|---|
| Case diameter | 38.5 mm, as reported by Fratello in 2025 |
| Lug-to-lug | 45.2 mm, as reported by Fratello in 2025 |
| Thickness | 10.4 mm, as reported by Fratello in 2025 |
| Case material | Grade 5 titanium, according to Fratello’s 2025 article |
| Crystal | Flat sapphire with inner anti-reflective coating, according to Fratello’s 2025 article |
| Caseback | Screw-in titanium, according to Fratello’s 2025 article |
| Water resistance | 10 ATM / 100 m, as reported by Fratello in 2025 |
| Movement | Miyota 9039 automatic; manual winding and hacking; 28,800 vph; 24 jewels; 42-hour power reserve, as reported by Fratello in 2025 |
| Functions | Hours, minutes and seconds; no date is listed in Fratello’s 2025 specification |
| Strap on 2025 variants | 20 mm black German-made calfskin strap, leather from Perlinger tannery, with Grade 2 titanium pin buckle, according to Fratello |
These figures are published specifications, not measurements independently verified for this review. A 38.5 mm diameter and 45.2 mm lug-to-lug length point to relatively compact proportions on paper, but fit still depends on wrist shape, strap flexibility and personal preference. The cited coverage does not establish how the watch wears or how durable it is in daily use.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals.

- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Case, movement and everyday use
Titanium case and water resistance
The 2025 specification lists a Grade 5 titanium case and a 100 m rating. Those details suggest a sports-watch brief, but the rating alone does not establish performance in real-world conditions, and no durability or water-resistance testing is reported in the cited coverage. Confirm the maker’s care and service guidance before exposing any watch to water.
Miyota 9039 and time-only layout
The reported Miyota 9039 is an automatic movement with manual winding and hacking, allowing the wearer to wind it by hand and stop the seconds hand while setting the time. Its published 42-hour reserve means it may stop if left unworn beyond that interval; the exact run time of an individual watch is not established. The layout keeps the display to hours, minutes and seconds, with no date listed. That is clean and simple if you prefer a date-free dial, but less convenient if you routinely use a date display.

Dial and strap options in the coverage
Lake Blue and Misty Green
Fratello’s June 13, 2025 article describes these dials as two-layer sandwich constructions, with Super-LumiNova BGW9 indices. It lists the black calfskin strap and titanium pin buckle as the accompanying setup. Whether the colors or strap suit you is subjective; the cited article does not provide a controlled legibility comparison.
Earlier turquoise, copper and dark brown versions
The May 2024 hands-on article describes original dial centers in turquoise, copper or dark brown and a gray canvas strap with leather lining and titanium hardware. The strap change matters if you prefer a textile feel over calfskin, but the articles do not establish that either strap configuration can be selected with every dial or is available now.
Rank #3

Some commenters on the 2024 article expressed preferences about the distinctive hands and the minute/seconds markings, while others noted the absent date. Those are individual reactions, not a measured flaw or a settled consensus. Inspect the dial design closely if hand shape, scale markings or a date window are important to you.

Is the J&Berg B2 a good choice?
The published feature set makes the B2 a plausible option for someone seeking a compact, time-only titanium sports watch with an automatic movement and unusual dial colors. Its trade-offs are equally clear: no date, a distinctive design that may not suit every taste, and a leather strap on the 2025 versions rather than the earlier canvas setup. The cited coverage supplies specifications and editorial impressions, not a controlled comparison with alternatives such as Boldr or RZE, nor independently verified durability results.
Before buying, check the current price and whether the exact dial and strap combination is actually in stock in your region. Confirm fit against your wrist using both the 38.5 mm case diameter and 45.2 mm lug-to-lug measurement, and decide whether the time-only layout, hands and dial markings work for you. For water use, rely on current maker guidance rather than treating a published rating as a guarantee of real-world condition.
