Breitling Top Time B31 38 vs. B01 41
The Top Time B31 38 and B01 41 share current manufacture credentials and 100 m ratings, but they answer different questions. B31 is a compact three-hand/date watch; B01 is a larger automatic chronograph with pushers, registers and a more overt motorsport identity.
This comparison uses AB3113281A1X1 on beige calfskin and AB01763A1C1X1 Shelby Cobra on brown calfskin. No price is stored in the guide.
Top Time B31 38 and B01 41 specification matrix
| Exact reference | Function | Case | Movement / reserve | Water | Selected attachment |
|---|---|---|---|---|---|
| AB3113281A1X1 | Three hands and date | 38 × 10.31 mm steel | Breitling B31 (Manufacture) / approx. 78 h | 100 m | Beige calfskin, tang buckle |
| AB01763A1C1X1 | Two-register chronograph | 41 × 13.3 mm steel | Breitling 01 (Manufacture) / approx. 70 h | 100 m | Brown calfskin, folding clasp |
B31 and B01 are not versions of the same function
Manufacture Calibre B31 is a self-winding three-hand movement with date and an approximately 78-hour reserve. It removes chronograph pushers and registers, giving the 38 mm Top Time a cleaner dial and simpler daily interaction.
Manufacture Calibre 01 is a self-winding chronograph. In AB01763A1C1X1 it records quarter seconds and elapsed minutes and is listed with an approximately 70-hour reserve. Choose B01 because the chronograph function and fuller dashboard-inspired display are wanted—not because manufacture status separates it from B31.
The B01 41 has materially more physical and visual presence
The B31 is 38 × 10.31 mm. The selected B01 is 41 × 13.3 mm, making it 3 mm larger in diameter and 2.99 mm thicker. Both use approximately 20 mm in-between-lug widths, but the B01 adds pushers and a folding clasp while the selected B31 uses a tang buckle.
The B31 is the more cuff-friendly and visually restrained option. The B01 creates greater dial density and wrist presence. Neither is universally better: upper-wrist width, preferred chronograph scale, strap exit and clasp comfort decide the fit.
The 65.84 g and 54 g figures belong only to AB3113281A1X1
Breitling's official product copy lists a 65.84 g total weight and a 54 g watch-head weight for AB3113281A1X1. That complete reference is the beige calfskin-strap configuration with a tang buckle.
The cited official B01 product page does not provide a directly comparable complete-watch weight in the specifications used here, so this guide makes no numeric B31-versus-B01 weight claim. Diameter and thickness can be compared; unmatched configuration weight cannot.
Quiet dashboard influence or explicit chronograph identity
Choose B31 38
For a compact manufacture automatic, cleaner dial, date, longer listed reserve and the thinner case.
Choose B01 41
For automatic chronograph function, pushers, twin-register visual density and the Shelby Cobra execution.
Choose by exact edition
Automotive branding, dial, caseback, strap and limitation status must be verified by full reference.
Both selected references are rated to 100 m and use fixed bezels and non-screw-locked crowns with two gaskets. That shared rating does not erase the functional difference between the watches, and it does not prove the current seal condition of a pre-owned example.
Chronograph testing for B01; date and reserve testing for B31
On B31, inspect winding, date change, reserve, crown feel and display-caseback condition. On B01, test start, stop and reset repeatedly, confirm clean zero return and inspect pusher action. On both, review crystal coating, dial printing, hands, case transitions, strap, buckle or clasp and documentation.
For the Shelby Cobra reference, confirm the exact dial emblem, colorway, caseback and supplied strap rather than trusting a model nickname. An automotive association does not by itself establish limitation, originality or condition.
Before water use, obtain an appropriate recent pressure test and follow the operating instructions. Do not operate chronograph pushers in water.

Top Time B31 38 vs. B01 41 FAQs

No. AB3113281A1X1 is a three-hand/date automatic. AB01763A1C1X1 is the automatic chronograph in this comparison.
Which selected Top Time is thinner?

Which movement has the longer listed reserve?
B31 is listed at approximately 78 hours, while B01 is listed at approximately 70 hours.
Do both selected Top Times have the same water rating?
Yes. Both exact references are officially rated to 100 m, subject to the individual watch's maintained seal condition.
Does the Top Time B31 bracelet watch weigh 65.84 grams?
That figure must not be used for the bracelet watch. Breitling's 65.84 g total and 54 g watch-head figures are tied here only to calfskin-strap reference AB3113281A1X1.
Why is there no numeric weight comparison with the B01 41?
The cited official B01 page does not provide a directly comparable complete-watch weight, and unmatched strap or bracelet weights would be misleading.
Is the Shelby Cobra Top Time automatically a limited edition?
No. Verify limitation status and all edition claims against the complete reference rather than inferring them from the automotive name.
