ochs und junior ochs line two time zones + date

Ludwig Oechslin introduces due ore mese – or two time zones + date – for the first time as a series-produced watch in the ochs und junior ochs line. The two time zones are displayed simultaneously via a uniquely designed hour hand, distinguishing this watch from all other ochs und junior models. This original Oechslin timepiece is powered by the Ulysse Nardin UN-118 movement, offering a 60-hour power reserve.

While the ochs und junior due ore / two time zones, available in the ochs line as a series-produced watch with an ETA movement since 2022, displays the time in two different time zones, the due ore mese / two time zones + date, powered by the UN-118, also allows the date to be read simultaneously.

ochs und junior introduces this original timepiece from its ochs line, combining elegance, originality, and functionality. It is housed in a 42mm grade 5 titanium case and features a PVD brown, roundground dial (Pantone No. 7553 C) that subtly shifts in color depending on the light. The second time zone disc, date disc, seconds disc, and power reserve disc are presented in the same shade for a cohesive design.

The markers, second time zone numbers, hour and minute hands, seconds dot, and power reserve dot are finished in a warm sandy tone (Pantone No. 7506 C ), offering a refined contrast.

For nighttime readability, Superluminova is applied to indices, hands, and numerals.

The watch is delivered with an Ecopell leather strap in Coconut, available in sizes Small, Medium, Large, and X-Large. Both strap and leather pouch are handmade by Sabina Brägger.

Less is more – both an art and a philosophy, transcending continents and time zones

With just 10 individual components and powered by the UN-118 caliber, this timepiece keeps you connected to loved ones or business partners across continents and time zones – all on a clearly readable, specific date.

Mechanics

The following parts were designed by Ludwig Oechslin specifically for his two time zones + date.

1. Direction gear
2. Gear wheel
3. Timezones disc
4. Date disc
5. Module board (titanium provides the right elasticity for the spring visible on the left side of this part, which holds the timezone disk in place)
6. Dial
7. Hour hand
8. Minute hand
9. Seconds disc
10. Power reserve indicator

The base movement is the Ulysse Nardin UN-118.

The two time zones + date offers two different functions in one crown position

Oechslin’s two time zones + date watch contains a mechanism that allows two of the watch’s functions to be set using the same crown position. In position 1, turning the crown counterclockwise sets the timezone, while turning it clockwise sets the date.

The direction gear that makes this possible is fairly common in watchmaking. What’s ingenious, however, is how it’s used in this context and how the two functions interact. The timezone disc is controlled by the date disc. Changing the direction of rotation while setting the watch causes the direction gear to disengage, breaking the connection between the timezone disc and the date disc. This ensures that force is applied only to the timezone disc during adjustment.

While the watch is running, no additional gears interact with the timezone disc, ensuring optimal power transfer from the base movement. The titanium spring that holds the timezone disc in position is integrated directly into the module board, greatly simplifying assembly of the mechanism.

Oechslin’s two time zones + date watch thus contains a mechanism that combines and connects functions, yet also separates them when necessary.

Reading the functions

The hands display the first time zone. The number inside the open hour hand indicates the second time zone. The timezone disc in the center is adjusted so that the time difference between the two zones is displayed at 12 o’clock.

If the second time zone is ahead (e.g., +3 hours), you set that number at 12 o’clock. If the second time zone is behind, subtract the difference from 12 and set the result at 12 o’clock.

Both time zones are displayed in 12-hour format. It is assumed that the user knows whether the second time zone is ahead or behind the first.

The 30+1 holes around the perimeter of the dial display the date. The 10-minute markers serve as reference points. For example, the 30-minute marker also represents the 15th day of the month (30 ÷ 2 = 15). These 5-day markers make it easy to read the date at a glance. After a short while, you’ll intuitively recognize the date without counting.

The small circle beneath the 12 o’clock marker is the power reserve indicator. When the dot is aligned with the rightmost 12 o’clock marker, the watch is fully wound (60 hours). When the dot reaches the leftmost marker, the power reserve is empty. The disc rotates counterclockwise.

The exact minute can be read using the date holes, which are spaced at 2-minute intervals. Holes represent even minutes; the gaps between them represent odd minutes.

Just above the 6 o’clock marker is a seconds disc with a milled eccentric dot. This disc confirms that the watch is running.
