Investment Watches 2026 — Which References Preserve and Appreciate

"Investment Watches" in the Thai Market 2026 — A Realistic Framework

Before recommending "investment-grade" references, the framework requires honesty: watches are illiquid alternative assets with maintenance costs. Long-term 5–10 year returns on well-chosen pieces run 4–8% per annum (per the WatchCharts Overall Market Index 2014–2024) — versus Thai SET Index 5–7% per annum.

Watches as an investment carry:

• Holding costs — service ฿20k–฿80k every 5–8 years + insurance 0.3–0.6%/year
• Sale fees — auction 18–22%, dealer markup 8–15%
• Illiquidity — selling at a good price takes 1–6 months
• Currency risk — global watch markets trade in USD/CHF; THB fluctuates

A "good investment watch" needs:

1. Large and continuous collector base
2. Declining supply (discontinued or limited)
3. In-house caliber collectors value
4. Trackable reference history

Five Picks for 2026

1. AP Royal Oak Selfwinding 15400ST (discontinued 2019)

June 2026 price: ฿880,000–฿1,180,000 (median ฿1,070,000)

Investment thesis:

• Discontinued for 7 years — supply continues to thin
• Now trades about ฿160,000 (10–15%) below the current 15500ST — the old discontinued premium has reversed, which makes it the cheaper way into a 41mm Royal Oak
• Caliber 3120 commands collector premium
• Date window preserves Tapisserie — detail collectors weight

Risks: Down about 40% from its April 2022 peak (฿1,783,000) and roughly flat over the past year (−0.9%); AP may redesign and overshadow 15400ST aesthetic; service occasionally requires Switzerland routing

5-year forecast: +18–28% (price floor already rationalised)

2. Patek Philippe Nautilus 5712/1A

June 2026 price: ฿3,200,000–฿3,800,000 (median ฿3,500,000)

Investment thesis:

• Discontinued 2022 — supply declining
• About ฿300,000 below the 5711 (median ฿3,800,000) but with more complications
• 5711 hype faded — 5712 attention should rise
• Micro-rotor caliber 240 PS IRM C LU is a collector caliber

Risks: Down about 31.5% from its March 2022 peak (฿5,112,000) and roughly flat over the past year (−1.1%) — there is no recovery in the data yet; Patek may release a 5712 successor; complication market sentiment hard to time

5-year forecast: +20–35% (catch-up trade vs 5711)

3. Rolex Daytona 116500LN (discontinued 2023)

June 2026 price: ฿730,000–฿1,120,000 (median ฿890,000)

Investment thesis:

• Discontinued 3 years — supply down 12% YoY
• "Modern discontinued" Rolex collectors actively seek
• White panda dials trade about ฿90,000–฿145,000 above black
• Caliber 4130 is signature

Risks: 126500LN successor may absorb demand; potential Rolex reissue

5-year forecast: +15–25%

4. Tudor Black Bay 58 79030 (sub-฿200k segment)

October 2026 estimate: ฿90,000–฿125,000 (WatchCharts US$3,049 for the 79030N at ฿32.5/USD)

Investment thesis:

• Entry-tier in-house caliber + COSC = value floor
• "Best value diver" reputation is durable
• Rolex DNA at about a quarter of a used Submariner's price
• Tudor's 2024 and 2026 MSRP rises apply to the newer Black Bay 58 (about US$4,300 pre-owned, WatchScanning); the discontinued 79030 has not followed them

Risks: Tudor produces high volume; MSRP increases may slow

5-year forecast: none. The 79030 is discontinued and trades below its final US list price of about US$3,920, so buy it to wear, not to profit

5. AP Royal Oak Jumbo Extra-Thin 16202ST (50th Anniversary)

October 2026 estimate: ฿2,450,000–฿2,755,000 (WatchCharts market range US$75,423–84,711 at ฿32.5/USD)

Investment thesis:

• 50th anniversary Royal Oak release (2022)
• Caliber 7121 in-house (replacing 2121)
• Limited production allocation
• "Jumbo" 39mm proportion is a collector dream

Risks: AP may phase out or refresh; tier 1 entry sometimes lacks liquidity

5-year forecast: none. It already trades at about twice its US$40,100 US retail price, so any further gain depends on AP keeping supply tight

What We Don't Recommend as Investment

Rolex Submariner 126610LN

• Price: ฿385,000–฿465,000
• Why not: Supply expanding 2025–2026, MSRP rises annually, collector premium thinning. Returns 3–6%/year — below actively managed funds

Rolex Datejust 41 126334

• Price: ฿250,000–฿420,000 (median ฿365,000)
• Why not: Very high supply, 8–10%/year depreciation, most Datejust collectors don't sell

Omega Speedmaster Moonwatch 310.30

• Price: ฿185,000–฿225,000
• Why not: Entry tier — high production volume, heritage value but not scarce, low collector premium

Hublot Big Bang Unico

• Why not: 12–15%/year depreciation, narrow collector base, brand strategy focused on production volume

Portfolio Approach

For a ฿15M watch portfolio:

• 40% Patek + AP top references (Nautilus 5712, Royal Oak 15400ST, RO Jumbo 16202ST), "blue chip"
• 25% Rolex discontinued (Daytona 116500LN, Submariner 116610LN before 126610LN): "stable growth"
• 20% Complications (Patek Annual Calendar, IWC Perpetual) — "horological premium"
• 10% Vintage (5-digit Rolex, vintage Patek) — "long-term capital gains"
• 5% Tudor + Cartier entry — "liquidity buffer"

Service + Storage Costs

Account for these when calculating returns.
