Louis Erard and Konstantin Chaykin have given the Frog Princess two new skins: Unfrogettable Turquoise (85340AA03.BVA192) and Unfrogettable Brown (85340AA04.BVA193). Same rotated-regulator face, same 12-o’clock tiara crown, same Grade 5 titanium case. Official brand pages published 21 September 2026 print a 40 mm satin-and-polished titanium case, 5 bar / 50 m, Sellita SW266-1, CHF 4,500 excluding tax, and a 178-piece limit per colour.

Lug-to-lug and thickness are not on the 2026 PDP accordion. The official 2025 Unfrogettable press kit — same case family — prints 46.50 mm tip-to-tip and 12.45 mm thick. 2026 press (Monochrome, Chronopassion) reprints those numbers for Turquoise and Brown. Treat 46.5 / 12.45 as verified press-kit geometry, not a 2026 PDP line. Ordering this pass is an official Waiting list / “Notify me when available” path — Shopify marks both SKUs unavailable. That is not live stock, and we do not invent a wait, an allocation, or a Singapore tray.

Fit literacy filter

Lead on official Ø40 mm and Grade 5 titanium, then flag L2L 46.5 / 12.45 as press-kit (2025 official kit + 2026 press; omitted on the live accordion). Ø40 sits just above the 36–39 mm 6.5" diameter band; 46.5 sits in the upper half of the 45–48 mm try-on filter. Titanium and wrapping lugs may help drape — that is geometry talk, not a proven on-wrist. Soft FX-only ~S$7.0k–~S$7.3k from CHF 4,500 ex tax — not SG RRP; verify taxes and shipping at checkout. Official path is the brand waiting list, not a cart. See lug-to-lug, fit checker, and dress.

Official numbers (Louis Erard PDP + labelled press)

Both official PDPs agree on satin-finished and polished Grade 5 titanium, 40 mm diameter, sapphire with anti-reflective treatment on both sides, a see-through caseback, and water resistance of 5 bars (50 m / 165 ft). The automatic is Sellita SW266-1 — regulator architecture, hours / minutes / seconds, minimum 38-hour reserve. Brand copy: a 178-piece limited edition developed with Konstantin Chaykin, and a three-year warranty. List price on both pages is CHF 4,500 Excl. Tax.

What the accordion does not print: tip-to-tip, thickness, or lug width. Those sit on the November 2025 official press kit hosted by Chaykin — Ø40 / lug-to-lug 46.50 / thickness 12.45, 20/18 mm strap, 31 jewels, 28,800 vph, élaboré grade, openworked oscillating weight with the black-lacquered Louis Erard symbol. Monochrome’s 2026 first look and Chronopassion’s Turquoise sheet reprint 40 × 12.45 × 46.5 for these colourways. We do not invent a new span from the photos.

Two colourways — same case, different metal accents

Turquoise is the louder face: official copy prints a dark turquoise and purple hour ring, a light-turquoise grained lower plate, dark-turquoise lacquered nostrils, and rhodium-treated discs plus an arrow minute hand with SLN C5 green tips. Purple stitching and a purple rabbit-leather lining sit on the black Himeji Kurozan strap. The hidden love note — Louis Erard and Konstantin Chaykin joined by a heart — lives in the violet segment of the minute track.

Brown warms the same geometry: dark brown and ochre hour ring, light-brown grained plate, dark-brown nostrils, and 5N-plated discs, minute hand, and crown. Official strap copy here is black stitching and a black leather lining — more tonal than Turquoise. Both keep the frog’s eyes as the regulator: hours revolving at 9, seconds at 3, minutes on the periphery.

Fit on ~6.5″ — caution / plausible, not proven

On a ~6.5" (≈165 mm) wrist, WristFit’s starting band is roughly 36–39 mm diameter and 45–48 mm lug-to-lug. Official Ø40 sits just above that diameter filter. Press-kit 46.50 mm L2L sits inside the span band but toward the longer half — not a short-lug hero, not an automatic fail. Press-kit 12.45 mm is a cuff-edge stack: under the 13 mm thickness bump in the fit checker, thicker than a dress-flat 10.

Two things may help, and we will not dress them up as a try-on. The case is Grade 5 titanium, so mass should be lower than a steel 40 of the same volume. The lugs wrap around the case to clear the 12-o’clock crown — press describes that wrap as helping the watch sit; that is brand/press language, not a WristFit on-wrist measurement. We did not invent a 6.5" wear photo. Official brand lifestyle stills exist on the PDPs; we are not republishing them as proof of fit.

Score it caution / plausible: diameter and published span are slightly proud of the compact targets; titanium and wrapping lugs are reasons to stay curious, not reasons to skip a try-on. The fit checker can use 46.5 if you accept the press-kit span; it cannot turn that into a Low overhang stamp without your wrist and a real strap drape. See sizing and 6.5" wrist size.

Soft SGD / Singapore buying path

Authoritative list is CHF 4,500 excluding tax on both official PDPs. There is no published Singapore RRP this pass. Soft FX only from that CHF ticket, at a mid-September 2026 CHFSGD class of about 1.55–1.62: roughly ~S$7.0k–~S$7.3k. That is orientation, not a published SG RRP, not a landed total, not a WristFit quote. Card FX, checkout taxes, and shipping sit outside the band. Do not convert a French AD euro tag (Chronopassion prints €5,850 TTC as a retailer figure) into a second Singapore price.

Singapore path: both official pages show a Klaviyo Waiting list control and “Notify me when available.” Shopify JSON this pass marks 85340AA03.BVA192 and 85340AA04.BVA193 unavailable / sold out. That is the honest order path — join the brand list, then verify the live cart if a slot opens. Brand chrome also lists Singapore in the country picker (CHF) and a general “worldwide shipping” / “taxes, discounts and shipping calculated at checkout” note. Confirm ship-to-SG, duties, and GST on the live checkout; we do not invent a DDP promise or a duty percentage. CIF on CHF 4,500 will sit well above IRAS’s S$400 air/post relief threshold if the watch ever ships here. See IRAS — importing goods, Singapore buying, and Band 3.

We did not find a published local tray or an official Singapore boutique listing for these two SKUs this pass. Chronopassion’s “nouveauté en attente” is a Paris AD wait, not an SG allocation. Do not invent a wait time, a raffle, or “in stock at Sincere.”

Comparison — Ø / thick / L2L in compact dress-adjacent

Model Ø Thick L2L Fit note (~6.5")
LE × Chaykin Unfrogettable Turquoise / Brown 40 12.45 press-kit 46.5 press-kit Caution / plausible; Ti + wrap lugs may help; waiting list; no SG RRP
Grand Seiko SBGW325 37.3 11.7 official 44.3 official Shorter published span; flagged dress height; SG boutique path
Kurono Calendrier SBR Saxe Blue 38 10 / 11.5 incl crystal Unpublished Stronger Ø; missing span; DTC USD drop window
Timex Atelier GMT Première 38 38 13.8 official 46.11 official Similar span class, thicker GMT stack — the thickness trap cousin
Omega Aqua Terra 38 38.0 12.2 45.0 official Shorter published span at a smaller Ø; AD try-on path

Reality check

Turquoise and Brown are a timely ~6.5" caution — official Ø40 titanium, press-kit 46.5 × 12.45 — not a proven short-lug hero. L2L and thickness are not on the 2026 PDP accordion; we cite the 2025 official kit and 2026 press, and we will not invent a new span from packshots. Fit is caution / plausible: wrapping lugs and titanium may help, but there is no WristFit on-wrist. Soft ~S$7.0k–~S$7.3k is FX orientation on CHF 4,500 ex tax, not a Singapore RRP and not a landed total. Verify taxes and shipping at checkout. The live brand control is a waiting list — do not read that as stock, a wait time, or a local allocation.
