Two things happened to the 8号 this week, and they point in opposite directions.
It became a Grand Prix d’Horlogerie de Genève finalist.
It is also, right now, impossible to buy.
If you want the background on why a Tokyo workshop of four people has collectors setting alarms for the middle of the night, that is our canonical piece on Ōtsuka Lōtec. This one is about what moved.
Nominated. Petite Aiguille. November 7.
On September 1 the brand posted the notice: the 8号 is a nominated timepiece in the Petite Aiguille category at GPHG 2026, the class for watches under 10,000 Swiss francs.
Six watches made that category. The 8号 is in a field with Christopher Ward, Frédérique Constant, Massena LAB, MING x J.N. Shapiro, and TAG Heuer.
Read that list twice.
One of those names is a four-person shop in Ōtsuka.
The ceremony is November 7, 2026 in Geneva. Before that the nominated watches tour: Mumbai September 28 to October 1, Bangkok October 15 to 18, Geneva October 29 to November 15, London November 18 to 23.
Why this is not a first
Katayama has been here before. The 6号 took the Challenge prize in 2024, the category for watches under 3,000 Swiss francs. That was the year the outside world learned the name: the 6号 won at Geneva, the 7.5号 took an iF Design Award, and in November the Ministry of Health, Labour and Welfare named Katayama a Contemporary Master Craftsman.
So the pattern is now two nominations across two price brackets, two years apart, for a workshop that has never built a movement from scratch for a production watch. The 8号 runs on a Miyota base like the rest of the line. What gets nominated is what Katayama builds around it.
That distinction matters and the brand has never hidden it. Neither should anyone writing about it.
And You Still Cannot Buy One
Here is the part nobody put a notice out about.
The 8号 came off the BASE storefront in late August. Its item page returns a 404. Not sold out, not marked closed. Gone. The shop category showed four models. It now shows three: the 5号改 at ¥825,000, the 6号 at ¥495,000, the 7.5号 at ¥396,000.
A week has now passed and it has not come back.
Put it against the calendar. On August 25 the brand posted a price revision citing materials, distribution, and labor. Effective September 1, 2026, the 8号 goes to ¥1,089,000 including tax, up from ¥990,000. That date has passed. The listing has not returned.
What we can say, and what we are guessing
We work casebacks for a living, so we keep these two columns apart on purpose.
What the evidence shows:
- The 8号 is not enterable or purchasable through the shop today.
- The published revision took effect September 1. The next 8号 round is a ¥1,089,000 card authorization, not ¥990,000.
- The notice names only the 8号. The 5号改 draw one week out at an unchanged ¥825,000 is the proof the rest of the line did not move.
- Anyone telling you Ōtsuka Lōtec raised prices across the catalog is wrong.
What we are inferring: the pull is housekeeping ahead of the new number, and the listing comes back when there is a round to attach it to. A missing page is evidence. The reason is a guess, and we are going to keep labeling it as one until the brand says otherwise.
The uncomfortable version is simpler. The most decorated watch in the current lineup, nominated in Geneva on September 1, has no door to walk through as of September 6.
Seven Days to the 5号改
The door that is opening belongs to the 5号改, and it opens next Sunday.
- Registration window: September 13, 2026, 17:00 to 23:30 JST
- Results: September 18, 2026 at 18:00 JST
- Price: ¥825,000 including tax, unchanged
- Listing: a brand new item page, not the old one reopened
That last line is the kind of thing you only catch by diffing the shop week over week, which is exactly what this column is. The brand does not reopen a closed draw. It builds a fresh listing every round, which is why old pages sit there forever displaying a registration period that expired months ago.
We have watched collectors read a stale window as a live one. Check the year. Check the date. A dead window is not cleared out. It just sits there looking official.
What the window looks like from Texas
17:00 JST is 3:00 a.m. Central. The window shuts at 23:30 JST, which is 9:30 a.m. Central.
Six and a half hours. In Japanese. Between the middle of the night and the middle of a Sunday morning in the United States.
The 5号改 is the satellite-hour piece that joined the MIH permanent collection in La Chaux-de-Fonds this past April alongside the 6号. It is not the cheapest way into the brand and it is not the trophy. It is a museum piece you can theoretically be assigned by lottery, which is a strange sentence that is nonetheless true.
The 9号: Still Nothing, Still the Wrong Door
Weekly status on the question we get most. The 9号 has not appeared on the BASE shop. No listing, no window, no waitlist.
¥17,600,000. Jumping hours, rewinding minutes, tourbillon, hour striking, power reserve. The first in-house complication and the reason the international press learned the name.
Our read has not changed, and this week reinforced it. The brand spent September 2 through 6 at Geneva Watch Days, its first international booth, in a building full of exactly the people a ¥17.6 million watch gets placed with directly. That watch is not going through a public draw. Refreshing the shop page for a 9号 listing is watching a door that is not going to open.
Where We Sit
We will be entering the September 13 round. One entry, one name, one address, on the pledge, as collectors.
We hold the two things a round requires and almost no American does: a Japanese domestic shipping address and a Japanese-issued credit card. That took years to assemble for reasons that had nothing to do with this brand, and the background piece explains why the second one stops nearly everybody.
What we will not do, and we get asked every single time: we will not enter on your behalf and we will not proxy-buy. The brand refuses resale-motivated entries, requires a separate pledge, and rejects every entry sharing a name or address rather than quietly deduplicating them. We sell watches for a living. We still think that policy is correct, and running around it would make us the exact problem it was built to stop.
If you want to see one in the metal without winning anything, Isetan Shinjuku has run a permanent display with TAKANO since July 8, 2026. It is still the only counter on earth where you can stand in front of these.
What We Are Watching
- Whether the 8号 returns to the shop at ¥1,089,000, and whether a round comes with it.
- Anything filed out of Geneva Watch Days now that the show has closed.
- The September 18 results announcement, which confirms the round closed on schedule.
- Whether a GPHG finalist badge changes entry volume on the next 8号 draw. Our guess is yes, and not in our favor.
- November 7 in Geneva.
A watch you cannot buy got nominated for one of the sport’s real prizes this week. That is not a contradiction. That is the whole brand in one sentence.
The vintage and pre-owned side of the hunt is where we actually have inventory: casebackchron.com/shop. The new-release side of the market gets covered daily on our Substack, where Buying Retail is Optional.
Set an alarm for 3:00 a.m. Central on the 13th.
Or do not, and read about it here on the 18th.
